Check Digit Verification of cas no

The CAS Registry Mumber 81657-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81657-75:
(7*8)+(6*1)+(5*6)+(4*5)+(3*7)+(2*7)+(1*5)=152
152 % 10 = 2
So 81657-75-2 is a valid CAS Registry Number.
