Check Digit Verification of cas no

The CAS Registry Mumber 1221689-33-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,6,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1221689-33:
(9*1)+(8*2)+(7*2)+(6*1)+(5*6)+(4*8)+(3*9)+(2*3)+(1*3)=143
143 % 10 = 3
So 1221689-33-3 is a valid CAS Registry Number.

Hydroperoxides and aryl diazonium salts as reagents for the functionalization of non-activated olefins

Blank, Olga,Raschke, Nicole,Heinrich, Markus R.

supporting information; experimental part, p. 1758 - 1760 (2010/04/29)

Hydroperoxides, olefins, and arenediazonium salts selectively combine to give azo compounds via an iron(II)-mediated three-component reaction. Starting with a fragmentation liberating acetic acid, the hydroperoxides act as radical source and the diazonium ions as nitrogen-centered radical scavengers.
