69502-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69502-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69502-91:
(7*6)+(6*9)+(5*5)+(4*0)+(3*2)+(2*9)+(1*1)=146
146 % 10 = 6
So 69502-91-6 is a valid CAS Registry Number.

Asymmetric synthesis using reactions with modest group selectivity
Ward, Dale E.,Liu, YaDong,Rhee, Chung K.
, p. 1429 - 1446 (2007/10/02)
The isomeric purity of products from certain group-selective reactions can be significantly amplified when reactions can occur sequentially.The theoretical basis for a strategy that exploits reactions with modest enantiotopic group selectivity for asymmet
