7267-05-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7267-05-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7267-05:
(6*7)+(5*2)+(4*6)+(3*7)+(2*0)+(1*5)=102
102 % 10 = 2
So 7267-05-2 is a valid CAS Registry Number.
