Check Digit Verification of cas no

The CAS Registry Mumber 388-91-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 388-91:
(5*3)+(4*8)+(3*8)+(2*9)+(1*1)=90
90 % 10 = 0
So 388-91-0 is a valid CAS Registry Number.
