5267-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5267-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,6 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5267-38:
(6*5)+(5*2)+(4*6)+(3*7)+(2*3)+(1*8)=99
99 % 10 = 9
So 5267-38-9 is a valid CAS Registry Number.
