Check Digit Verification of cas no

The CAS Registry Mumber 138857-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138857-70:
(8*1)+(7*3)+(6*8)+(5*8)+(4*5)+(3*7)+(2*7)+(1*0)=172
172 % 10 = 2
So 138857-70-2 is a valid CAS Registry Number.
