Check Digit Verification of cas no
The CAS Registry Mumber 20207-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20207-20:
(7*2)+(6*0)+(5*2)+(4*0)+(3*7)+(2*2)+(1*0)=49
49 % 10 = 9
So 20207-20-9 is a valid CAS Registry Number.
