6340-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6340-98-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6340-98:
(6*6)+(5*3)+(4*4)+(3*0)+(2*9)+(1*8)=93
93 % 10 = 3
So 6340-98-3 is a valid CAS Registry Number.
