Check Digit Verification of cas no

The CAS Registry Mumber 1421864-74-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,8,6 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1421864-74:
(9*1)+(8*4)+(7*2)+(6*1)+(5*8)+(4*6)+(3*4)+(2*7)+(1*4)=155
155 % 10 = 5
So 1421864-74-5 is a valid CAS Registry Number.
