20137-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20137-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,3 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 20137-81:
(7*2)+(6*0)+(5*1)+(4*3)+(3*7)+(2*8)+(1*1)=69
69 % 10 = 9
So 20137-81-9 is a valid CAS Registry Number.
