Check Digit Verification of cas no

The CAS Registry Mumber 215675-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,6,7 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215675-67:
(8*2)+(7*1)+(6*5)+(5*6)+(4*7)+(3*5)+(2*6)+(1*7)=145
145 % 10 = 5
So 215675-67-5 is a valid CAS Registry Number.
