Check Digit Verification of cas no

The CAS Registry Mumber 634154-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,1,5 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 634154-26:
(8*6)+(7*3)+(6*4)+(5*1)+(4*5)+(3*4)+(2*2)+(1*6)=140
140 % 10 = 0
So 634154-26-0 is a valid CAS Registry Number.
