Check Digit Verification of cas no

The CAS Registry Mumber 119720-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,2 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119720-67:
(8*1)+(7*1)+(6*9)+(5*7)+(4*2)+(3*0)+(2*6)+(1*7)=131
131 % 10 = 1
So 119720-67-1 is a valid CAS Registry Number.

SYNTHESIS OF 1,2-GLYCOL MONOETHERS UTILIZING DECARBONYLATION OF α-ALKOXYACID CHLORIDES MEDIATED BY SAMARIUM DIIODIDE

Sasaki, Mitsuru,Collin, Jacqueline,Kagan, Henri B.

, p. 4847 - 4850 (1988)

A new synthesis of 1,2-glycol monoethers has been achived by utilizing decarbonylation of α-alkoxyacid chlorides mediated by samarium diiodide in the presence of ketones.This one-pot reaction works within a few minutes at room temperature.The structure of α-alkoxyacid chlorides (R2,R3)C(OR1)COCl2 tolerates various substitution patterns (R2=R3=H; R2=H; R3=Me or R2=R3=Me).
