Check Digit Verification of cas no

The CAS Registry Mumber 220929-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,2 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220929-44:
(8*2)+(7*2)+(6*0)+(5*9)+(4*2)+(3*9)+(2*4)+(1*4)=122
122 % 10 = 2
So 220929-44-2 is a valid CAS Registry Number.
