23469-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23469-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,6 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 23469-50:
(7*2)+(6*3)+(5*4)+(4*6)+(3*9)+(2*5)+(1*0)=113
113 % 10 = 3
So 23469-50-3 is a valid CAS Registry Number.
