Check Digit Verification of cas no

The CAS Registry Mumber 548943-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,9,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 548943-40:
(8*5)+(7*4)+(6*8)+(5*9)+(4*4)+(3*3)+(2*4)+(1*0)=194
194 % 10 = 4
So 548943-40-4 is a valid CAS Registry Number.

Fast and highly efficient one-pot synthesis of 9-deazaxanthines

Stefanachi, Angela,Leonetti, Francesco,Cappa, Anna,Carotti, Angelo

, p. 2121 - 2123 (2003)

SnCl2 enables a direct, high-yield conversion of 5-nitro-1,3-dialkyl-6-styryl(furyl-, thienyl-vinyl)-uracils to 8-substituted-9-deazaxanthines under very mild experimental conditions. The method has a general applicability and it is compatible with the reactivity of the most common organic functional groups. In slightly experimental different conditions, it allows a high-yield and fast (5 min) preparation of pure 7-N-hydroxy-9-deazaxanthines.
