91246-55-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91246-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91246-55:
(7*9)+(6*1)+(5*2)+(4*4)+(3*6)+(2*5)+(1*5)=128
128 % 10 = 8
So 91246-55-8 is a valid CAS Registry Number.
