Check Digit Verification of cas no

The CAS Registry Mumber 1609253-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,2,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1609253-99:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*5)+(3*3)+(2*9)+(1*9)=177
177 % 10 = 7
So 1609253-99-7 is a valid CAS Registry Number.

Facile synthesis of thieno[2,3-d]pyrimidine derivatives using inorganic base catalysis

Meng, Shuangming,Jia, Zhifang,Wang, Kewei,Fan, Yueqin,Guo, Yong

, p. 1461 - 1465 (2014/05/20)

Potassium carbonate as inorganic base catalyst was used to develop an efficient synthetic procedure for the preparation of thieno[2,3-d]pyrimidine derivatives. The molecular structure of the newly synthesized compounds were confirmed by NMR spectral data.
