20124-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20124-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,2 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20124-42:
(7*2)+(6*0)+(5*1)+(4*2)+(3*4)+(2*4)+(1*2)=49
49 % 10 = 9
So 20124-42-9 is a valid CAS Registry Number.
