Check Digit Verification of cas no

The CAS Registry Mumber 1233680-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,6,8 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1233680-69:
(9*1)+(8*2)+(7*3)+(6*3)+(5*6)+(4*8)+(3*0)+(2*6)+(1*9)=147
147 % 10 = 7
So 1233680-69-7 is a valid CAS Registry Number.
