4933-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4933-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4933-67:
(6*4)+(5*9)+(4*3)+(3*3)+(2*6)+(1*7)=109
109 % 10 = 9
So 4933-67-9 is a valid CAS Registry Number.
