Check Digit Verification of cas no

The CAS Registry Mumber 1393911-96-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,9,1 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1393911-96:
(9*1)+(8*3)+(7*9)+(6*3)+(5*9)+(4*1)+(3*1)+(2*9)+(1*6)=190
190 % 10 = 0
So 1393911-96-0 is a valid CAS Registry Number.

One-pot synthesis of thieno [2,3-d] pyrimidin-4-ol derivatives mediated by polyphosphonic anhydride

Poojari, Subba,Parameswar Naik,Krishnamurthy

experimental part, p. 4639 - 4643 (2012/09/05)

An efficient synthesis of thiopyrimidines with different substituents in position 2 is described. A rapid, mild and high yielding microwave-assisted one-pot cyclization of 5-substituted 2-amino thiophene-3-carboxamide derived from Gewald reaction1 with T3P and different acids gives the corresponding thiopyrimidines. The significant feature of this method includes less reaction time, high purity and reduced toxicity of the reaction.
