123723-77-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123723-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,2 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123723-77:
(8*1)+(7*2)+(6*3)+(5*7)+(4*2)+(3*3)+(2*7)+(1*7)=113
113 % 10 = 3
So 123723-77-3 is a valid CAS Registry Number.

TAUTOMERISM OF SACCHARIDE HYDRAZONES IN SOLUTION AND THEIR REACTION WITH NITROUS ACID

Williams, Michael J.

, p. 89 - 94 (1983)

N.m.r. spectroscopy (13C and 1H) has been used to show that saccharide hydrazones in solution in hydrazine exist mainly as the syn acyclic-tautomer.In deoterium oxide solutions, slow tautomerisation occours to give glycosylhydrazines; at pH 6 tautomerism is rapid and the latter preponderate; exceptions are the hydrazones of D-ribose and L-arabinose which give almost equal proportions of acyclic and cyclic tautomers at pH 6.Reaction of representative saccharide hidrazones with nitrous acid gives a mixture of the corresponding saccharide and the β-glycosyl azide, the latter being formed from the glycosylhydrazine tautomer.
