Check Digit Verification of cas no

The CAS Registry Mumber 1253-34-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1253-34:
(6*1)+(5*2)+(4*5)+(3*3)+(2*3)+(1*4)=55
55 % 10 = 5
So 1253-34-5 is a valid CAS Registry Number.
