Check Digit Verification of cas no

The CAS Registry Mumber 133589-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,8 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133589-31:
(8*1)+(7*3)+(6*3)+(5*5)+(4*8)+(3*9)+(2*3)+(1*1)=138
138 % 10 = 8
So 133589-31-8 is a valid CAS Registry Number.

Cobalt(II) Catalyzed Coupling Reaction of α,β-Unsaturated Compounds with Aldehydes by the Use of Phenylsilane. New Method for Preparation of β-Hydroxy Nitriles, Amides, and Esters

Isayama, Shigeru,Mukaiyama, Teruaki

, p. 2005 - 2008 (2007/10/02)

A new crossed coupling reaction of α,β-unsaturated nitriles with aldehydes was performed by using phenylsilane and a catalytic amount of bis(1,3-diketonato)cobalt(II) to give β-siloxy nitriles in good yields.Similarly, α,β-unsaturated amides and esters also reacted under the same conditions to afford β-siloxy amides or esters.The present reaction provides a new and facile method for preparation of β-hydroxy nitriles, amides, and esters.
