54653-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54653-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54653-30:
(7*5)+(6*4)+(5*6)+(4*5)+(3*3)+(2*3)+(1*0)=124
124 % 10 = 4
So 54653-30-4 is a valid CAS Registry Number.
