681843-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 681843-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,8,4 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 681843-66:
(8*6)+(7*8)+(6*1)+(5*8)+(4*4)+(3*3)+(2*6)+(1*6)=193
193 % 10 = 3
So 681843-66-3 is a valid CAS Registry Number.
