Check Digit Verification of cas no

The CAS Registry Mumber 82881-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,8 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82881-02:
(7*8)+(6*2)+(5*8)+(4*8)+(3*1)+(2*0)+(1*2)=145
145 % 10 = 5
So 82881-02-5 is a valid CAS Registry Number.

REACTIONS OF CYCLIC ENAMINES WITH DICYANOMETHYLENECYCLOPROPENES. FORMATION OF MEDIUM RING COMPOUNDS AND TRANSANNULATION TO FULVENES

Tsuge, Otohiko,Okita, Shigeru,Noguchi, Michihiko,Kanemasa, Shuji

, p. 847 - 850 (2007/10/02)

Several cyclic enamines with five to seven-membered rings react with 2-(1,2-diphenyl-3-cyclopropenylidene)propanedinitrile to give medium ring compounds, showing that the latter is a versatile reagent which can insert three carbon atoms between α- and β-c
