Check Digit Verification of cas no

The CAS Registry Mumber 138565-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,6 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138565-06:
(8*1)+(7*3)+(6*8)+(5*5)+(4*6)+(3*5)+(2*0)+(1*6)=147
147 % 10 = 7
So 138565-06-7 is a valid CAS Registry Number.
