Check Digit Verification of cas no

The CAS Registry Mumber 1381990-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,9,9 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1381990-64:
(9*1)+(8*3)+(7*8)+(6*1)+(5*9)+(4*9)+(3*0)+(2*6)+(1*4)=192
192 % 10 = 2
So 1381990-64-2 is a valid CAS Registry Number.

Mesoionic oxides: Facile access from triazolium salts or triazolylidene copper precursors, and catalytic relevance

Petronilho, Ana,Mueller-Bunz, Helge,Albrecht, Martin

supporting information; experimental part, p. 6499 - 6501 (2012/08/13)

Reaction of CsOH with triazolium salts affords mesoionic compounds containing an exocyclic oxygen; the same product is obtained by reaction of the corresponding Cu(i) triazolylidenes with CsOH and represents an unusual reactivity pattern of N-heterocyclic
