891-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891-99-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 891-99:
(5*8)+(4*9)+(3*1)+(2*9)+(1*9)=106
106 % 10 = 6
So 891-99-6 is a valid CAS Registry Number.
