81912-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81912-46-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,1 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81912-46:
(7*8)+(6*1)+(5*9)+(4*1)+(3*2)+(2*4)+(1*6)=131
131 % 10 = 1
So 81912-46-1 is a valid CAS Registry Number.
