Check Digit Verification of cas no

The CAS Registry Mumber 21538-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,3 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21538-06:
(7*2)+(6*1)+(5*5)+(4*3)+(3*8)+(2*0)+(1*6)=87
87 % 10 = 7
So 21538-06-7 is a valid CAS Registry Number.
