Check Digit Verification of cas no

The CAS Registry Mumber 100638-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,3 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100638-45:
(8*1)+(7*0)+(6*0)+(5*6)+(4*3)+(3*8)+(2*4)+(1*5)=87
87 % 10 = 7
So 100638-45-7 is a valid CAS Registry Number.
