6535-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6535-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6535-71:
(6*6)+(5*5)+(4*3)+(3*5)+(2*7)+(1*1)=103
103 % 10 = 3
So 6535-71-3 is a valid CAS Registry Number.
