"Starch, compd. with iodine" refers to a chemical complex formed when starch reacts with iodine molecules. Starch, compd. with iodine is commonly known as the iodine-starch complex or simply iodine-starch. It is formed when iodine molecules interact with the helical structure of starch, causing a color change to a deep blue or black hue. This reaction is utilized in various applications, such as detecting the presence of starch in food products or forensic analysis. The iodine-starch complex is also used in educational settings to demonstrate the chemical properties of starch and the behavior of iodine in different environments. The formation of this complex is based on the specific interaction between the hydroxyl groups in the starch molecules and the iodine molecules, which results in a change in the electronic structure and consequently the color of the solution.

Check Digit Verification of cas no

The CAS Registry Mumber 9005-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 9005-83:
(6*9)+(5*0)+(4*0)+(3*5)+(2*8)+(1*3)=88
88 % 10 = 8
So 9005-83-8 is a valid CAS Registry Number.
