Check Digit Verification of cas no

The CAS Registry Mumber 1262126-86-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,1,2 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1262126-86:
(9*1)+(8*2)+(7*6)+(6*2)+(5*1)+(4*2)+(3*6)+(2*8)+(1*6)=132
132 % 10 = 2
So 1262126-86-2 is a valid CAS Registry Number.

Lanthanum(III) isopropoxide catalyzed chemoselective transesterification of dimethyl carbonate and methyl carbamates

Hatano, Manabu,Kamiya, Sho,Moriyama, Katsuhiko,Ishihara, Kazuaki

supporting information; experimental part, p. 430 - 433 (2011/04/15)

A practical transesterification of less reactive dimethyl carbonate and much less reactive methyl carbamates with primary (1°), secondary (2°), and tertiary (3°) alcohols was established with the use of a lanthanum(III) complex, which was prepared in situ from lanthanum (III) isopropoxide (3 mol %) and 2-(2-methoxyethoxy)ethanol (6 mol %). In particular, corresponding carbonates and carbamates obtained were of synthetic utility from the viewpoint of the selective protection and/or deprotection of 1°-, 2°-, and 3°-alcohols.
