Check Digit Verification of cas no

The CAS Registry Mumber 167268-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,2,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167268-47:
(8*1)+(7*6)+(6*7)+(5*2)+(4*6)+(3*8)+(2*4)+(1*7)=165
165 % 10 = 5
So 167268-47-5 is a valid CAS Registry Number.
