1823-45-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1823-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1823-45:
(6*1)+(5*8)+(4*2)+(3*3)+(2*4)+(1*5)=76
76 % 10 = 6
So 1823-45-6 is a valid CAS Registry Number.
