247123-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247123-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,1,2 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 247123-89:
(8*2)+(7*4)+(6*7)+(5*1)+(4*2)+(3*3)+(2*8)+(1*9)=133
133 % 10 = 3
So 247123-89-3 is a valid CAS Registry Number.
