724767-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 724767-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,4,7,6 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 724767-19:
(8*7)+(7*2)+(6*4)+(5*7)+(4*6)+(3*7)+(2*1)+(1*9)=185
185 % 10 = 5
So 724767-19-5 is a valid CAS Registry Number.
