56054-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56054-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,5 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56054-56:
(7*5)+(6*6)+(5*0)+(4*5)+(3*4)+(2*5)+(1*6)=119
119 % 10 = 9
So 56054-56-9 is a valid CAS Registry Number.
