Check Digit Verification of cas no

The CAS Registry Mumber 770719-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,0,7,1 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 770719-79:
(8*7)+(7*7)+(6*0)+(5*7)+(4*1)+(3*9)+(2*7)+(1*9)=194
194 % 10 = 4
So 770719-79-4 is a valid CAS Registry Number.
