Check Digit Verification of cas no

The CAS Registry Mumber 220235-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220235-68:
(8*2)+(7*2)+(6*0)+(5*2)+(4*3)+(3*5)+(2*6)+(1*8)=87
87 % 10 = 7
So 220235-68-7 is a valid CAS Registry Number.
