Check Digit Verification of cas no

The CAS Registry Mumber 32202-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,0 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 32202-87:
(7*3)+(6*2)+(5*2)+(4*0)+(3*2)+(2*8)+(1*7)=72
72 % 10 = 2
So 32202-87-2 is a valid CAS Registry Number.

Formation of enehydrazine intermediates through coupling of phenylhydrazines with vinyl halides: Entry into the Fischer indole synthesis

Zhan, Fuxu,Liang, Guangxin

, p. 1266 - 1269 (2013/03/13)

Cut to the chase: Direct formation of an enehydrazine, an intermediate in the classic Fischer indole synthesis, solves the regioselectivity problem associated with indolization. This approach not only achieves selective synthesis of indoles through proper selection of the vinyl halide, but also leads to quick construction of desoxyeseroline and esermethole, as well as the key structural motif in the Akuammiline alkaloid vincorine.
