13997-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13997-20-1 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 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13997-20:
(7*1)+(6*3)+(5*9)+(4*9)+(3*7)+(2*2)+(1*0)=131
131 % 10 = 1
So 13997-20-1 is a valid CAS Registry Number.
