91322-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91322-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,2 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91322-89:
(7*9)+(6*1)+(5*3)+(4*2)+(3*2)+(2*8)+(1*9)=123
123 % 10 = 3
So 91322-89-3 is a valid CAS Registry Number.
