Check Digit Verification of cas no

The CAS Registry Mumber 79386-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,8 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79386-27:
(7*7)+(6*9)+(5*3)+(4*8)+(3*6)+(2*2)+(1*7)=179
179 % 10 = 9
So 79386-27-9 is a valid CAS Registry Number.
