124646-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124646-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,4 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124646-93:
(8*1)+(7*2)+(6*4)+(5*6)+(4*4)+(3*6)+(2*9)+(1*3)=131
131 % 10 = 1
So 124646-93-1 is a valid CAS Registry Number.

Kubo, Yuji,Kuwana, Minoru,Okamoto, Ken,Yoshida, Katsuhira
, p. 855 - 857 (1989)
New di-iminonaphthalene type near-i.r. dyes are conveniently synthesized by condensing 1-naphthylcyanamide with p-N,N-dialkylaminoanilines in the presence of an oxidising agent; their absorption properties are discussed.
