Check Digit Verification of cas no

The CAS Registry Mumber 212388-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,3,8 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 212388-57:
(8*2)+(7*1)+(6*2)+(5*3)+(4*8)+(3*8)+(2*5)+(1*7)=123
123 % 10 = 3
So 212388-57-3 is a valid CAS Registry Number.
