54347-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54347-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,4 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54347-72:
(7*5)+(6*4)+(5*3)+(4*4)+(3*7)+(2*7)+(1*2)=127
127 % 10 = 7
So 54347-72-7 is a valid CAS Registry Number.
