82741-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82741-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,4 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82741-93:
(7*8)+(6*2)+(5*7)+(4*4)+(3*1)+(2*9)+(1*3)=143
143 % 10 = 3
So 82741-93-3 is a valid CAS Registry Number.
