Check Digit Verification of cas no

The CAS Registry Mumber 72812-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,1 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72812-45:
(7*7)+(6*2)+(5*8)+(4*1)+(3*2)+(2*4)+(1*5)=124
124 % 10 = 4
So 72812-45-4 is a valid CAS Registry Number.

A Rapid and Efficient Synthesis of Sulfur Analogues of Pyrimidine Bases

Lapucha, Andrzej R.

, p. 256 - 258 (1987)

An improved procedure for thionation of some natural pyrimidine bases with tetraphosphorus decasulfide/sodium hydrogen carbonate is reported.Some substituted uracils and 2-thiouracils were converted into a series of analogues in which the oxygen at position 4 was replaced by sulfur atom.The advantage of this method of thionation over the older procedures is based on the tetraphosphorus decasulfide/sodium hydrogen carbonate mixture giving rise to excellent yields and simplified isolation of the desired pure products.
