81930-96-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81930-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,3 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81930-96:
(7*8)+(6*1)+(5*9)+(4*3)+(3*0)+(2*9)+(1*6)=143
143 % 10 = 3
So 81930-96-3 is a valid CAS Registry Number.
