52056-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52056-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,5 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52056-04:
(7*5)+(6*2)+(5*0)+(4*5)+(3*6)+(2*0)+(1*4)=89
89 % 10 = 9
So 52056-04-9 is a valid CAS Registry Number.
