Check Digit Verification of cas no

The CAS Registry Mumber 1657-32-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1657-32:
(6*1)+(5*6)+(4*5)+(3*7)+(2*3)+(1*2)=85
85 % 10 = 5
So 1657-32-5 is a valid CAS Registry Number.
