Check Digit Verification of cas no

The CAS Registry Mumber 1620839-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,8,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1620839-07:
(9*1)+(8*6)+(7*2)+(6*0)+(5*8)+(4*3)+(3*9)+(2*0)+(1*7)=157
157 % 10 = 7
So 1620839-07-7 is a valid CAS Registry Number.
