Check Digit Verification of cas no

The CAS Registry Mumber 1257649-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,6,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1257649-41:
(9*1)+(8*2)+(7*5)+(6*7)+(5*6)+(4*4)+(3*9)+(2*4)+(1*1)=184
184 % 10 = 4
So 1257649-41-4 is a valid CAS Registry Number.

Stereoselective synthesis of α-Diazo oxime ethers and their application in the synthesis of highly substituted pyrroles through a [3+2] cycloaddition

Lourdusamy, Emmanuvel,Yao, Lin,Park, Cheol-Min

supporting information; experimental part, p. 7963 - 7967 (2011/01/08)

The stereoselective diazo transfer reaction with oxime ethers offers an efficient route to the corresponding α-diazo oxime ethers. The utility of these compounds has been demonstrated by the synthesis of highly substituted pyrroles through a [3+2] cycloaddition of α-oximino carbenoids with enamines (see scheme).
