157428-24-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157428-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,2 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157428-24:
(8*1)+(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*2)+(1*4)=145
145 % 10 = 5
So 157428-24-5 is a valid CAS Registry Number.
