57647-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57647-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57647-74:
(7*5)+(6*7)+(5*6)+(4*4)+(3*7)+(2*7)+(1*4)=162
162 % 10 = 2
So 57647-74-2 is a valid CAS Registry Number.
