Check Digit Verification of cas no

The CAS Registry Mumber 1209001-75-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,9,0,0 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1209001-75:
(9*1)+(8*2)+(7*0)+(6*9)+(5*0)+(4*0)+(3*1)+(2*7)+(1*5)=101
101 % 10 = 1
So 1209001-75-1 is a valid CAS Registry Number.

Efficient and library-friendly synthesis of furo- and thieno[2,3-d] pyrimidin-4-amine derivatives by microwave irradiation

Han, Ying,Ebinger, Katalin,Vandevier, Lauren E.,Maloney, Jennifer W.,Nirschl, David S.,Weller, Harold N.

experimental part, p. 629 - 632 (2010/04/05)

A new, divergent, efficient, and selective synthesis of furo- and thieno[2,3-d]pyrimidin-4-amine derivatives by microwave irradiation has been developed starting from readily available amines and substituted 2-aminofuran-3-carbonitrile or 2-aminothiophene-3-carbonitrile, which are converted into corresponding formamidines in DMF using benzenesulfonyl chloride.
