Check Digit Verification of cas no

The CAS Registry Mumber 1237764-75-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1237764-75:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*6)+(3*4)+(2*7)+(1*5)=178
178 % 10 = 8
So 1237764-75-8 is a valid CAS Registry Number.

An efficient synthesis of 6,9-disubstituted purin-8-ones via copper-catalyzed coupling/cyclization

Zhong, Qi-Fei,Sun, Li-Ping

, p. 5107 - 5111 (2010)

An efficient and novel synthesis of 6,9-disubstituted purin-8-ones has been developed. Starting from dichloropyrimidin-5-ylcarbamate, CuCl/amino acid catalyzed coupling/cyclization reaction with amines was achieved to afford 9-substituted 6-chloropurin-8-ones. Then a microwave-assisted amination procedure was carried out for the synthesis of 6,9-disubstituted purin-8-ones in moderate to good yields.
