Check Digit Verification of cas no

The CAS Registry Mumber 643768-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,6 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 643768-18:
(8*6)+(7*4)+(6*3)+(5*7)+(4*6)+(3*8)+(2*1)+(1*8)=187
187 % 10 = 7
So 643768-18-7 is a valid CAS Registry Number.
