55243-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55243-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55243-88:
(7*5)+(6*5)+(5*2)+(4*4)+(3*3)+(2*8)+(1*8)=124
124 % 10 = 4
