Check Digit Verification of cas no
The CAS Registry Mumber 14072-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14072-20:
(7*1)+(6*4)+(5*0)+(4*7)+(3*2)+(2*2)+(1*0)=69
69 % 10 = 9
So 14072-20-9 is a valid CAS Registry Number.
