52747-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52747-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,4 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52747-68:
(7*5)+(6*2)+(5*7)+(4*4)+(3*7)+(2*6)+(1*8)=139
139 % 10 = 9
So 52747-68-9 is a valid CAS Registry Number.
