Check Digit Verification of cas no
The CAS Registry Mumber 209404-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,4,0 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209404-26:
(8*2)+(7*0)+(6*9)+(5*4)+(4*0)+(3*4)+(2*2)+(1*6)=112
112 % 10 = 2
So 209404-26-2 is a valid CAS Registry Number.
