136347-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136347-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,4 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136347-12:
(8*1)+(7*3)+(6*6)+(5*3)+(4*4)+(3*7)+(2*1)+(1*2)=121
121 % 10 = 1
So 136347-12-1 is a valid CAS Registry Number.

Reactions of chiral β-ketosulfoxides with Et2AlCN: Asymmetric synthesis of cyanohydrin derivatives
Garcia Ruano,Martin Castro,Rodriguez
, p. 3195 - 3198 (2007/10/02)
The reaction of chiral p-tolylsulfinylmethyl ketones (R-CO-CH2-SOTol, R=Ph, Et and t-Bu) with Et2AlCN, yields almost optically pure sulfinyl cyanohydrins (d.e. ≥ 96%). The reaction was quicker in the presence of ZnCl2, but
