Check Digit Verification of cas no

The CAS Registry Mumber 81281-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,8 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81281-47:
(7*8)+(6*1)+(5*2)+(4*8)+(3*1)+(2*4)+(1*7)=122
122 % 10 = 2
So 81281-47-2 is a valid CAS Registry Number.

A FACILE CONVERSION OF THE 1-METHYL GROUP TO THE 1-AMINO GROUP OF XANTHINE DERIVATIVES

Ueda, Taisei,Oda, Noriichi,Sakakibara, Jinsaku,Takeya, Kazumi

, p. 2291 - 2294 (2007/10/02)

A facile conversion of the 1-methyl group to the 1-amino group of caffeine and its analogues was carried out by the reaction with hydrazine hydrate: Refluxing of caffeine (Ia) with a large amount of hydrazine hydrate (30 eq. mole) without any other solvents gave 1-amino-3,7-dimethylxanthine (IIa) in 40percent yield.Similarly the reaction of 7-substituted 1,3-dimethylxanthines (Ib,Id-f) with hydrazine hydrate gave 7-substituted 1-amino-3-methylxanthines (IIb, IId-f) in 28-42percent yield.Deamination of these 7-substituted 1-amino-3-methylxanthines (IIa-b, IId-f) gave the corresponding theobromine derivatives (IVa-b, IVd-f) in 90-96percent yield.
