Check Digit Verification of cas no

The CAS Registry Mumber 1189-65-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1189-65:
(6*1)+(5*1)+(4*8)+(3*9)+(2*6)+(1*5)=87
87 % 10 = 7
So 1189-65-7 is a valid CAS Registry Number.
