Check Digit Verification of cas no

The CAS Registry Mumber 13642-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,4 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13642-52:
(7*1)+(6*3)+(5*6)+(4*4)+(3*2)+(2*5)+(1*2)=89
89 % 10 = 9
So 13642-52-9 is a valid CAS Registry Number.
