66406-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66406-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,0 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66406-81:
(7*6)+(6*6)+(5*4)+(4*0)+(3*6)+(2*8)+(1*1)=133
133 % 10 = 3
So 66406-81-3 is a valid CAS Registry Number.
