Check Digit Verification of cas no

The CAS Registry Mumber 22910-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,1 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22910-83:
(7*2)+(6*2)+(5*9)+(4*1)+(3*0)+(2*8)+(1*3)=94
94 % 10 = 4
So 22910-83-4 is a valid CAS Registry Number.
