Check Digit Verification of cas no

The CAS Registry Mumber 222045-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,0,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 222045-70:
(8*2)+(7*2)+(6*2)+(5*0)+(4*4)+(3*5)+(2*7)+(1*0)=87
87 % 10 = 7
So 222045-70-7 is a valid CAS Registry Number.
