Check Digit Verification of cas no

The CAS Registry Mumber 1269662-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,6,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1269662-40:
(9*1)+(8*2)+(7*6)+(6*9)+(5*6)+(4*6)+(3*2)+(2*4)+(1*0)=189
189 % 10 = 9
So 1269662-40-9 is a valid CAS Registry Number.

experimental part, p. 1878 - 1887 (2011/04/22)

A facile synthesis of potential acetylcholinesterase (AChE) inhibitors, the tacrine analogues 3a-p, has been accomplished by direct cyclocondensation of 1-aryl-4- cyano-5-aminopyrazole with β-ketoesters using tin(IV) chloride as catalyst. The structures o
