Check Digit Verification of cas no

The CAS Registry Mumber 944798-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,7,9 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 944798-21:
(8*9)+(7*4)+(6*4)+(5*7)+(4*9)+(3*8)+(2*2)+(1*1)=224
224 % 10 = 4
So 944798-21-4 is a valid CAS Registry Number.
