Check Digit Verification of cas no

The CAS Registry Mumber 21136-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,3 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21136-34:
(7*2)+(6*1)+(5*1)+(4*3)+(3*6)+(2*3)+(1*4)=65
65 % 10 = 5
So 21136-34-5 is a valid CAS Registry Number.
