81946-89-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81946-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81946-89:
(7*8)+(6*1)+(5*9)+(4*4)+(3*6)+(2*8)+(1*9)=166
166 % 10 = 6
So 81946-89-6 is a valid CAS Registry Number.
