91759-86-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91759-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,5 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91759-86:
(7*9)+(6*1)+(5*7)+(4*5)+(3*9)+(2*8)+(1*6)=173
173 % 10 = 3
So 91759-86-3 is a valid CAS Registry Number.
