Check Digit Verification of cas no

The CAS Registry Mumber 15948-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,4 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 15948-52:
(7*1)+(6*5)+(5*9)+(4*4)+(3*8)+(2*5)+(1*2)=134
134 % 10 = 4
So 15948-52-4 is a valid CAS Registry Number.
