Check Digit Verification of cas no

The CAS Registry Mumber 152931-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,3 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 152931-75:
(8*1)+(7*5)+(6*2)+(5*9)+(4*3)+(3*1)+(2*7)+(1*5)=134
134 % 10 = 4
So 152931-75-4 is a valid CAS Registry Number.
