99741-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99741-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,4 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99741-28:
(7*9)+(6*9)+(5*7)+(4*4)+(3*1)+(2*2)+(1*8)=183
183 % 10 = 3
So 99741-28-3 is a valid CAS Registry Number.

, p. 315 - 319 (2007/10/03)
A series of 1,1 -disubstituted taurines was synthesized expeditiously from ketones via the Corey-Chaykovsky epoxidation with dimethylsulfonium methylide, episulfidation with potassium sulfocyanate, ring-opening reaction with ammonia in the presence of sil
