93554-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93554-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,5 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93554-21:
(7*9)+(6*3)+(5*5)+(4*5)+(3*4)+(2*2)+(1*1)=143
143 % 10 = 3
So 93554-21-3 is a valid CAS Registry Number.
