3743-84-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3743-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3743-84:
(6*3)+(5*7)+(4*4)+(3*3)+(2*8)+(1*4)=98
98 % 10 = 8
So 3743-84-8 is a valid CAS Registry Number.
