If one is unsure whether he recited Birchas Hatorah, is he to recite the blessing?
Some Poskim rule one is to recite the blessing of Birchas Hatorah in a case that he is in doubt if he recited it. Others rule it is not to be recited. Practically one is not to repeat the blessing. If one did not yet Daven he should have in mind to fulfill his obligation in Davening. In such a case it is permitted for him to learn Torah prior to Davening. Alternatively one should hear the blessing from someone else. Alternatively one is to receive an Aliya to the Torah. This law applies whether one is in doubt whether he said any of the three blessings or only one of the three blessings, and either way he is not to repeat any blessing of which there is a doubt. According to all, women are not to recite Birchas Hatorah if they are in doubt if they said it.
 See Beir Heiytiv 47/1; Shaareiy Teshuvah 47/1; Kaf Hachaim 47/2; M”B 47/1; This question is dependent on whether one views Birchas Hatorah as Biblical or Rabbinical.
 Peri Chadash 47/1; Shaagas Aryeh 25 brought in Shaareiy Teshuvah 47/1; Derech Chaim 4/6
Which blessing is one to repeat? One is to repeat only the blessing of “Asher Bachar Banu”. [Shaagas Aryeh ibid; Derech Chaim ibid; M”B ibid] However the Peri Chadash ibid rules one is to say all three blessings.
 As according to these opinions Birchas Hatorah is Biblical and hence is repeated in a case of doubt, as rules Michaber in 209/3 regarding Birchas Hamazon.
 Mateh Yehuda 1; Machazik Bracha 47/1-2 brought in Shaareiy Teshuvah 47/1; Kesher Gudal 5/25; Beis Oveid 22; Nesiv Hachaim 4/6; Ksav Sofer 20; Shulchan Hatahor 47/3; Tehila Ledavid 47/1; Birchas Habayis 34/15; Kisei Eliyahu 47/1; Yifei Laleiv 47/1;
Ruling of Michaber: In 209/3 the Michaber rules that if one is in doubt if he recited one of the blessings, then he may not recite that blessing with exception to Birchas Hamazon being that it is a Biblical command. This implies that Birchas Hatorah is Rabbinical and is not to be said in a case of doubt. [Kaf Hachaim 47/2]
Ruling of Admur: See Admur 47/6 which rules in the case of dispute of whether one may say Birchas Hatorah if he already Davened, that one may not repeat the blessing. However see 47/7 that if one did not sleep at night he is to say the blessing even though there is doubt. See Likkutei Sichos 14 p. 148 footnote 7 that possibly according to Admur it is a Biblical obligation.

 Kaf Hachaim ibid; If one knows for certain that he said one of the blessings and is in doubt regarding the other blessings, some write that according to all he has already fulfilled his Biblical obligation and is hence not to repeat the blessing. [See Shaagas Aryeh 25; Piskeiy Teshuvos 47/2]
