13994-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13994-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,9 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13994-88:
(7*1)+(6*3)+(5*9)+(4*9)+(3*4)+(2*8)+(1*8)=142
142 % 10 = 2
So 13994-88-2 is a valid CAS Registry Number.
