56511-21-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56511-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,1 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56511-21:
(7*5)+(6*6)+(5*5)+(4*1)+(3*1)+(2*2)+(1*1)=108
108 % 10 = 8
So 56511-21-8 is a valid CAS Registry Number.
