Check Digit Verification of cas no

The CAS Registry Mumber 634465-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,4,6 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634465-89:
(8*6)+(7*3)+(6*4)+(5*4)+(4*6)+(3*5)+(2*8)+(1*9)=177
177 % 10 = 7
So 634465-89-7 is a valid CAS Registry Number.
