Check Digit Verification of cas no
The CAS Registry Mumber 7306-20-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7306-20:
(6*7)+(5*3)+(4*0)+(3*6)+(2*2)+(1*0)=79
79 % 10 = 9
So 7306-20-9 is a valid CAS Registry Number.
