Check Digit Verification of cas no
The CAS Registry Mumber 207-11-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 207-11:
(5*2)+(4*0)+(3*7)+(2*1)+(1*1)=34
34 % 10 = 4
So 207-11-4 is a valid CAS Registry Number.

El-Shaieb, Kamal M.
experimental part, p. 1150 - 1155 (2009/12/04)
1-(Dicyanomethylene)acenaphthene-2-one (1) reacts with 1,8- diaminonaphthalene (2) to yield two products, identified as acenaphtho[1,2-b] naphtho[1,8-ef][1,4]diazepine (3) and (Z)-2-(8-aminonaphthalen-1-ylamino)-2-(2- oxoacenaphthylen-1(2H)-ylidene)aceton
