Check Digit Verification of cas no

The CAS Registry Mumber 496790-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,6,7,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 496790-44:
(8*4)+(7*9)+(6*6)+(5*7)+(4*9)+(3*0)+(2*4)+(1*4)=214
214 % 10 = 4
So 496790-44-4 is a valid CAS Registry Number.
