17916-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17916-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17916-91:
(7*1)+(6*7)+(5*9)+(4*1)+(3*6)+(2*9)+(1*1)=135
135 % 10 = 5
So 17916-91-5 is a valid CAS Registry Number.
