Check Digit Verification of cas no

The CAS Registry Mumber 223505-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,0 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 223505-38:
(8*2)+(7*2)+(6*3)+(5*5)+(4*0)+(3*5)+(2*3)+(1*8)=102
102 % 10 = 2
So 223505-38-2 is a valid CAS Registry Number.
