16933-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16933-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,3 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16933-56:
(7*1)+(6*6)+(5*9)+(4*3)+(3*3)+(2*5)+(1*6)=125
125 % 10 = 5
So 16933-56-5 is a valid CAS Registry Number.
