20338-26-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20338-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,3 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20338-26:
(7*2)+(6*0)+(5*3)+(4*3)+(3*8)+(2*2)+(1*6)=75
75 % 10 = 5
So 20338-26-5 is a valid CAS Registry Number.
