Check Digit Verification of cas no

The CAS Registry Mumber 1268344-84-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,3,4 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1268344-84:
(9*1)+(8*2)+(7*6)+(6*8)+(5*3)+(4*4)+(3*4)+(2*8)+(1*4)=178
178 % 10 = 8
So 1268344-84-8 is a valid CAS Registry Number.
