Check Digit Verification of cas no

The CAS Registry Mumber 77902-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,0 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77902-86:
(7*7)+(6*7)+(5*9)+(4*0)+(3*2)+(2*8)+(1*6)=164
164 % 10 = 4
So 77902-86-4 is a valid CAS Registry Number.
