1643-95-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1643-95-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1643-95:
(6*1)+(5*6)+(4*4)+(3*3)+(2*9)+(1*5)=84
84 % 10 = 4
So 1643-95-4 is a valid CAS Registry Number.
