Check Digit Verification of cas no

The CAS Registry Mumber 444790-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,7,9 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 444790-79:
(8*4)+(7*4)+(6*4)+(5*7)+(4*9)+(3*0)+(2*7)+(1*9)=178
178 % 10 = 8
So 444790-79-8 is a valid CAS Registry Number.
