14283-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14283-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,8 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14283-69:
(7*1)+(6*4)+(5*2)+(4*8)+(3*3)+(2*6)+(1*9)=103
103 % 10 = 3
So 14283-69-3 is a valid CAS Registry Number.
