Check Digit Verification of cas no

The CAS Registry Mumber 25379-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,7 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25379-87:
(7*2)+(6*5)+(5*3)+(4*7)+(3*9)+(2*8)+(1*7)=137
137 % 10 = 7
So 25379-87-7 is a valid CAS Registry Number.

A CONVENIENT SYNTHESIS OF 3-(ARYL)SUBSTITUTED 2,4(1H,3H)-PTERIDINEDIONES AND THEIR ABSORPTION AND FLUORESCENCE SPECTROSCOPIC CHARACTERISTICS

Katoh, Akira,Ohkanda, Junko,Sato, Hiroshi,Sakamoto, Tsuyosi,Mitsuhashi, Keiryo

, p. 949 - 954 (1993)

3-(Aryl)substituted 2,4(1H,3H)-pteridinediones are synthesized in high yields by addition and simultaneous cyclization of methyl 3-amino-2-pyrazinecarboxylate with isocyanates.The remarcable difference in the reactivity is observed among heterocumulenes.The absorption and fluorescence spectroscopic characteristics of the titled compounds are also discussed.
