Check Digit Verification of cas no

The CAS Registry Mumber 20787-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,8 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20787-49:
(7*2)+(6*0)+(5*7)+(4*8)+(3*7)+(2*4)+(1*9)=119
119 % 10 = 9
So 20787-49-9 is a valid CAS Registry Number.
