145211-96-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145211-96-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,1 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 145211-96:
(8*1)+(7*4)+(6*5)+(5*2)+(4*1)+(3*1)+(2*9)+(1*6)=107
107 % 10 = 7
So 145211-96-7 is a valid CAS Registry Number.

Asymmetric aldol reactions employing a cyclic sulfamide chiral auxiliary
Ahn,Yoo,Kim
, p. 6661 - 6664 (1992)
A titanium enolate derived from (3S,4S)-2,5-dipropionyl-3,4-diphenyl-1,2,5-thiadiazolidine 1,1-dioxide (3) reacts with aldehydes to give syn aldols with high stereoselection (> 95:5).
