Check Digit Verification of cas no

The CAS Registry Mumber 21878-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,7 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21878-47:
(7*2)+(6*1)+(5*8)+(4*7)+(3*8)+(2*4)+(1*7)=127
127 % 10 = 7
So 21878-47-7 is a valid CAS Registry Number.
