20107-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20107-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,0 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20107-61:
(7*2)+(6*0)+(5*1)+(4*0)+(3*7)+(2*6)+(1*1)=53
53 % 10 = 3
So 20107-61-3 is a valid CAS Registry Number.
