Check Digit Verification of cas no
The CAS Registry Mumber 12009-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12009-21:
(7*1)+(6*2)+(5*0)+(4*0)+(3*9)+(2*2)+(1*1)=51
51 % 10 = 1
So 12009-21-1 is a valid CAS Registry Number.
