91906-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91906-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,0 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91906-19:
(7*9)+(6*1)+(5*9)+(4*0)+(3*6)+(2*1)+(1*9)=143
143 % 10 = 3
So 91906-19-3 is a valid CAS Registry Number.

Highly stereoselective construction of the C2 stereocentre of α-tocopherol (Vitamin E) by asymmetric addition of Grignard reagents to ketones

Bieszczad, Bartosz,Gilheany, Declan G.

, p. 6483 - 6492 (2017/08/16)

Tertiary alcohol precursors of both C2 diastereoisomers of α-tocopherol were prepared in three ways by our recently reported asymmetric Grignard synthesis. The versatility of Grignard chemistry inherent in its three-way disconnection was exploited to allow the synthesis of three product grades: 77:23 dr (5 steps), 81:19 dr (5 steps) and 96:4 dr (7 steps, one gram scale) from readily available and abundant starting materials. The products were converted to their respective α-tocopherols in 3 steps, which allowed a definitive re-assignment of their absolute configurations.
