Check Digit Verification of cas no

The CAS Registry Mumber 220643-48-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,4 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220643-48:
(8*2)+(7*2)+(6*0)+(5*6)+(4*4)+(3*3)+(2*4)+(1*8)=101
101 % 10 = 1
So 220643-48-1 is a valid CAS Registry Number.
