Check Digit Verification of cas no

The CAS Registry Mumber 92397-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,3,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92397-16:
(7*9)+(6*2)+(5*3)+(4*9)+(3*7)+(2*1)+(1*6)=155
155 % 10 = 5
So 92397-16-5 is a valid CAS Registry Number.
