20397-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20397-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20397-69:
(7*2)+(6*0)+(5*3)+(4*9)+(3*7)+(2*6)+(1*9)=107
107 % 10 = 7
So 20397-69-7 is a valid CAS Registry Number.
