Check Digit Verification of cas no

The CAS Registry Mumber 117013-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,0,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117013-23:
(8*1)+(7*1)+(6*7)+(5*0)+(4*1)+(3*3)+(2*2)+(1*3)=77
77 % 10 = 7
So 117013-23-7 is a valid CAS Registry Number.

HYDROXIDE-CATALYZED ISOMERIZATION OF D-(1-13C)MANNOSE: EVIDENCE FOR THE INVOLVEMENT OF 3,4-ENEDIOLS

King-Morris, Melinda J.,Serianni, Anthony S.

, p. 29 - 36 (2007/10/02)

The KOH-catalyzed isomerization of D-(1-13C)mannose under anaerobic conditions was studied by 13C-n.m.r. spectroscopy.D-(1-13C)Glucose and D-(1-13C)fructose are generated during the reaction, as expected.In addition, however, (6-13C)glucose, (6-13C)mannose, and (6-13C)fructose are produced in small proportions, possibly via symmetrical 3,4-enediol intermediates.The involvement of the latter structures in 13C-label shifting is inferred from the observation of (1-13C)sorbose and (6-13C)sorbose in the reaction mixture.
