137051-81-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137051-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,5 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137051-81:
(8*1)+(7*3)+(6*7)+(5*0)+(4*5)+(3*1)+(2*8)+(1*1)=111
111 % 10 = 1
So 137051-81-1 is a valid CAS Registry Number.

Factors that cause contrasteric alkylation of a cyclopentane-1,2-dicarboxylic acid monoester

Kigoshi,Imamura,Yoshikawa,Niwa,Yamada

, p. 4541 - 4544 (1991)

The stereochemical outcome in the alkylation of the enolate generated from a cyclopentane-1,2-dicarboxylic acid monoester is described. The alkylation of the Li enolate with an ankylating reagent having a hard leaving group such as Cl gave a contrasteric
