Check Digit Verification of cas no

The CAS Registry Mumber 922-19-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 922-19:
(5*9)+(4*2)+(3*2)+(2*1)+(1*9)=70
70 % 10 = 0
So 922-19-0 is a valid CAS Registry Number.
