Check Digit Verification of cas no

The CAS Registry Mumber 87872-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87872-40:
(7*8)+(6*7)+(5*8)+(4*7)+(3*2)+(2*4)+(1*0)=180
180 % 10 = 0
So 87872-40-0 is a valid CAS Registry Number.
