55338-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55338-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,3 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55338-12:
(7*5)+(6*5)+(5*3)+(4*3)+(3*8)+(2*1)+(1*2)=120
120 % 10 = 0
So 55338-12-0 is a valid CAS Registry Number.
