57436-32-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57436-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,3 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57436-32:
(7*5)+(6*7)+(5*4)+(4*3)+(3*6)+(2*3)+(1*2)=135
135 % 10 = 5
So 57436-32-5 is a valid CAS Registry Number.
