Formose sugars, also known as formose reaction products, are a group of complex carbohydrates formed through the formose reaction, a chemical process that simulates the prebiotic synthesis of sugars from formaldehyde. This reaction, discovered by Russian chemist Boris P. Toropov in 1861 and later refined by French chemist Louis-Henri Boullay in 1902, involves the condensation of formaldehyde molecules in the presence of a base, such as calcium hydroxide, to produce a mixture of sugars, including glyceraldehyde, dihydroxyacetone, and other polyols. Formose sugars are of significant interest in the study of the origins of life, as they represent potential precursors to the formation of ribose, a key component of RNA, and other biologically important sugars.

Check Digit Verification of cas no

The CAS Registry Mumber 8069-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 8069-42:
(6*8)+(5*0)+(4*6)+(3*9)+(2*4)+(1*2)=109
109 % 10 = 9
So 8069-42-9 is a valid CAS Registry Number.
