67909-26-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67909-26-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67909-26:
166 % 10 = 6
So 67909-26-6 is a valid CAS Registry Number.

An improved helferich method for the α/β-stereoselective synthesis of 4-methylumbelliferyl glycosides for the detection of microorganisms

, p. 21681 - 21699 (2015)

An improved Helferich method is presented. It involves the glycosylation of 4-methyl-umbelliferone with glycosyl acetates in the presence of boron trifluoride etherate combined with triethylamine, pyridine, or 4-dimethylaminopyridine under mild conditions, followed by deprotection to give fluorogenic 4-methylumbelliferyl glycoside substrates. Due to the use of base, the glycosylation reaction proceeds more easily, is uncommonly α- or β-stereoselective, and affords the corresponding products in moderate to excellent yields (51%-94%) under appropriate conditions.
