57234-61-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57234-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,3 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57234-61:
(7*5)+(6*7)+(5*2)+(4*3)+(3*4)+(2*6)+(1*1)=124
124 % 10 = 4
So 57234-61-4 is a valid CAS Registry Number.
