91486-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91486-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91486-89:
(7*9)+(6*1)+(5*4)+(4*8)+(3*6)+(2*8)+(1*9)=164
164 % 10 = 4
So 91486-89-4 is a valid CAS Registry Number.
