Check Digit Verification of cas no

The CAS Registry Mumber 57767-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,6 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57767-32:
(7*5)+(6*7)+(5*7)+(4*6)+(3*7)+(2*3)+(1*2)=165
165 % 10 = 5
So 57767-32-5 is a valid CAS Registry Number.
