Check Digit Verification of cas no

The CAS Registry Mumber 76169-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,6 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76169-06:
(7*7)+(6*6)+(5*1)+(4*6)+(3*9)+(2*0)+(1*6)=147
147 % 10 = 7
So 76169-06-7 is a valid CAS Registry Number.
