Check Digit Verification of cas no

The CAS Registry Mumber 137250-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,5 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137250-77:
(8*1)+(7*3)+(6*7)+(5*2)+(4*5)+(3*0)+(2*7)+(1*7)=122
122 % 10 = 2
So 137250-77-2 is a valid CAS Registry Number.

Anionic [3, 3] rearrangements of cyclic hydrazine diacylates to medium-size cyclic diamides and their structures

Endo, Yasuyuki,Uchida, Takuya,Yamaguchi, Kentaro

, p. 151 - 158 (2007/10/03)

The anionic rearrangement of N, N′-dimethyl-N, N′-diacylhydrazines to 1, 2-disubstituted succinamides proceeds in the presence of a ajacent enolatestabilizing substituent such as a phenyl group. However, a substituent that poorly stabilizes the cc-carbani

Anionic 3,4-diaza[3,3]sigmatropic rearrangements of N,N′-diacylhydrazines

Endo, Yasuyuki,Shudo, Koichi

, p. 4517 - 4520 (2007/10/02)

N,N′-Diacylhydrazines rearrange under basic conditions to afford 1,2-disubstituted succinamides. The rearrangement can be rationalized in terms of [3,3]sigmatropic shifts of biscarboxamide enolates.
