130012-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130012-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,1 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130012-70:
(8*1)+(7*3)+(6*0)+(5*0)+(4*1)+(3*2)+(2*7)+(1*0)=53
53 % 10 = 3
So 130012-70-3 is a valid CAS Registry Number.

A highly efficient and selective route to isomeric cyclic diazadienes
Scott, Mark E.,Bethuel, Yann,Lautens, Mark
, p. 1482 - 1483 (2007/10/03)
A highly selective Lewis acid-catalyzed ring expansion of methylenecyclopropyl hydrazones to isomeric cyclic diazadienes is reported. In general, good to excellent yields and selectivities were obtained for a broad range of hydrazone derivatives. Copyrigh
