7344-11-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7344-11-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7344-11:
(6*7)+(5*3)+(4*4)+(3*4)+(2*1)+(1*1)=88
88 % 10 = 8
So 7344-11-8 is a valid CAS Registry Number.
