Check Digit Verification of cas no
The CAS Registry Mumber 207124-96-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,1,2 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 207124-96:
(8*2)+(7*0)+(6*7)+(5*1)+(4*2)+(3*4)+(2*9)+(1*6)=107
107 % 10 = 7
So 207124-96-7 is a valid CAS Registry Number.

Novel synthesis and new chemistry of naphthochlorins
Krattinger, Benedicte,Nurco, Daniel J.,Smith, Kevin M.
, p. 757 - 758 (2007/10/03)
Reactions of 2-nitro-5,10,15,20-tetraphenylporphyrin with alkyl α-isocyanoacetates afford naphthochlorins (in addition to the expected pyrroloporphyrins) which undergo free radical dimerization; the X-ray structure of one such naphthochlorin dimer is repo
