57835-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57835-24-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,3 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57835-24:
(7*5)+(6*7)+(5*8)+(4*3)+(3*5)+(2*2)+(1*4)=152
152 % 10 = 2
So 57835-24-2 is a valid CAS Registry Number.
