Check Digit Verification of cas no

The CAS Registry Mumber 27649-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,4 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27649-51:
(7*2)+(6*7)+(5*6)+(4*4)+(3*9)+(2*5)+(1*1)=140
140 % 10 = 0
So 27649-51-0 is a valid CAS Registry Number.
