Check Digit Verification of cas no

The CAS Registry Mumber 777867-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,7,8,6 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 777867-86:
(8*7)+(7*7)+(6*7)+(5*8)+(4*6)+(3*7)+(2*8)+(1*6)=254
254 % 10 = 4
So 777867-86-4 is a valid CAS Registry Number.
