Check Digit Verification of cas no

The CAS Registry Mumber 1031391-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,3,9 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1031391-01:
(9*1)+(8*0)+(7*3)+(6*1)+(5*3)+(4*9)+(3*1)+(2*0)+(1*1)=91
91 % 10 = 1
So 1031391-01-1 is a valid CAS Registry Number.

A new entry to 1,5-keto esters and their 4,4-dideuterio derivatives via methylene chloride as methylene dianion equivalents

Lin, Kuo-Wei,Chen, G-Yih,Chen, Wei-Fan,Yan, Tu-Hsin

, p. 4759 - 4761 (2008)

(Chemical Equation Presented) This TiCl4-Mg promoted multicomponent coupling of various amides with CH2Cl2 and methyl acrylate represents an extremely simple and practical synthesis of 1,5-keto esters. The efficiency of this chemistry is illustrated by the very simple preparation of unusual 4,4-dideuterio- 1,5-keto esters.
