31880-33-8 Usage
General Description
.beta.-D-Mannofuranose, 1,6-anhydro- is a chemical compound that is a derivative of D-mannose, a type of sugar. It is a cyclic form of mannose with a furanose ring structure. The 1,6-anhydro- modification refers to the removal of a hydroxyl group at carbon 6, resulting in a six-membered cyclic ether ring. .beta.-D-Mannofuranose, 1,6-anhydro- has applications in the field of carbohydrate chemistry and can be used in the synthesis of various glycoside derivatives. It also has potential pharmaceutical applications due to its ability to interact with biological molecules and modify their activity.
Check Digit Verification of cas no
The CAS Registry Mumber 31880-33-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,8 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31880-33:
(7*3)+(6*1)+(5*8)+(4*8)+(3*0)+(2*3)+(1*3)=108
108 % 10 = 8
So 31880-33-8 is a valid CAS Registry Number.

Selective synthesis of 1,6-anhydro-β-D-mannopyranose and -mannofuranose using microwave-assisted heating

experimental part, p. 1747 - 1751 (2011/12/02)
The dehydration of D-mannose and the demethanolization of methyl-α-D-mannopyranoside (MαMP) or methyl-α-D- mannofuranoside (MαMF) were examined using microwave-assisted heating for a 3-min irradiation at temperature from 120 to 280 °C in ordinary or dry sulfolane without any catalyst. The microwave-assisted heating of MαMP and MαMF smoothly proceeded to selectively afford the anhydromannoses, 1,6-anhydro-β-D-mannopyranose (AMP) and 1,6-anhydro-β-D-mannofuranose (AMF), respectively, in high yields. For MαMP in ordinary sulfolane at 240 °C, AMP was selectively obtained in the AMF:AMP ratio of 4:96, whereas AMF was the major product at the AMF:AMP ratio of 97:3 from MαMF in dry sulfolane at 220 °C.
