137333-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137333-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137333-71:
(8*1)+(7*3)+(6*7)+(5*3)+(4*3)+(3*3)+(2*7)+(1*1)=122
122 % 10 = 2
So 137333-71-2 is a valid CAS Registry Number.

ENANTIOFACE-DIFFERENTIATING ADDITION OF A CHIRAL ARYLLITHIUM REAGENT TO ALDEHYDES
Asami, Masatoshi,Mukaiyama, Teruaki
, p. 17 - 20 (2007/10/02)
A chiral aryllithium reagent was prepared by treating a chiral aminal, derived from (S)-2-(anilinomethyl)pyrrolidine and o-bromobenzaldehyde, with n-butyl lithium.The chiral reagent reacted highly enantioface selectively with aliphatic aldehydes and, on h
