Check Digit Verification of cas no
The CAS Registry Mumber 12279-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12279-09:
(7*1)+(6*2)+(5*2)+(4*7)+(3*9)+(2*0)+(1*9)=93
93 % 10 = 3
So 12279-09-3 is a valid CAS Registry Number.
