817165-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 817165-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,7,1,6 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 817165-82:
(8*8)+(7*1)+(6*7)+(5*1)+(4*6)+(3*5)+(2*8)+(1*2)=175
175 % 10 = 5
So 817165-82-5 is a valid CAS Registry Number.
