637041-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637041-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 637041-40:
(8*6)+(7*3)+(6*7)+(5*0)+(4*4)+(3*1)+(2*4)+(1*0)=138
138 % 10 = 8
So 637041-40-8 is a valid CAS Registry Number.

, p. 2110 - 2114 (2007/10/03)
The Barbier approach was used for diastereoselective formation of allylamino acid derivatives. The stereochemical models for nucleophilic addition to N-tosylimines bearing various chiral auxiliaries such as (2R)-bornano-10,2-sultam, (R)-8-phenylmenthol, a
