Check Digit Verification of cas no

The CAS Registry Mumber 41280-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,2,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41280-45:
(7*4)+(6*1)+(5*2)+(4*8)+(3*0)+(2*4)+(1*5)=89
89 % 10 = 9
So 41280-45-9 is a valid CAS Registry Number.

Moskvichev, Yu.A.,Timoshenko, G.N.,Mironov, G.S.,Gracheva, S.G.,Kryukova, G.G.,Kozlova, O.S.

, p. 871 - 874 (2007/10/02)

The synthesis of trinuclear bridged aromatic sulfocarboxylic acids and their derivatives was realized by a series of consecutive reactions.The possibility of quantitative determination of the content of carboxyl, acid choride, sulfonyl chloride, and sulfonamide groups both in the monofunctional and in the bifunctional compounds was demonstrated by potentiometric titration.
