637020-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 637020-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,2 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 637020-39:
(8*6)+(7*3)+(6*7)+(5*0)+(4*2)+(3*0)+(2*3)+(1*9)=134
134 % 10 = 4
So 637020-39-4 is a valid CAS Registry Number.

Double Diastereoselection in Aldol Reactions Mediated by Dicyclohexylchloroborane between L-Erythrulose Derivatives and Chiral Aldehydes. The Felkin-Anh versus Cornforth Dichotomy

Marco, J. Alberto,Carda, Miguel,Diaz-Oltra, Santiago,Murga, Juan,Falomir, Eva,Roeper, Harald

, p. 8577 - 8582 (2007/10/03)

Both matched and mismatched diastereoselections have been observed in aldol reactions of the B,B-dicyclohexylboron enolate of a protected L-erythrulose derivative with a range of chiral aldehydes. The stereochemical outcome of reactions with α-methyl alde
