1535-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1535-47-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1535-47:
(6*1)+(5*5)+(4*3)+(3*5)+(2*4)+(1*7)=73
73 % 10 = 3
So 1535-47-3 is a valid CAS Registry Number.
