Check Digit Verification of cas no

The CAS Registry Mumber 94591-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,5,9 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94591-31:
(7*9)+(6*4)+(5*5)+(4*9)+(3*1)+(2*3)+(1*1)=158
158 % 10 = 8
So 94591-31-8 is a valid CAS Registry Number.

Pteridines, LXXV. - Synthesis and Properties of Biopterin and Biopterin Analogs

Kappel, Mathias,Mengel, Rolf,Pfleiderer, Wolfgang

, p. 1815 - 1825 (2007/10/02)

The synthesis of biopterin (6), its 2-N,N-dimethyl- (8) and 4-thioxo derivative (19) as well as biolumazine (7) is described.The side chain of biopterin can be modified by reaction of α-acetoxy-isobutyryl chloride to yield 6-(L-threo-2-acetoxy-1-chloropropyl)pterin (10), which can be used as a starting material for further derivatisations. 2,1',2'-Triacylbiopterins (14, 16) possess a hydrolytically labile N-acyl group.The newly synthesized compounds were characterized by pK-determinations, UV, and NMR spectra.
