123716-24-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123716-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,1 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123716-24:
(8*1)+(7*2)+(6*3)+(5*7)+(4*1)+(3*6)+(2*2)+(1*4)=105
105 % 10 = 5
So 123716-24-5 is a valid CAS Registry Number.
