Check Digit Verification of cas no

The CAS Registry Mumber 131771-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,7 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131771-47:
(8*1)+(7*3)+(6*1)+(5*7)+(4*7)+(3*1)+(2*4)+(1*7)=116
116 % 10 = 6
So 131771-47-6 is a valid CAS Registry Number.

Phosphate-catalyzed degradation of d-glucosone in aqueous solution is accompanied by C1-C2 transposition

Zhang, Wenhui,Serianni, Anthony S.

experimental part, p. 11511 - 11524 (2012/08/28)

Pathways in the degradation of the C6 1,2-dicarbonyl sugar (osone) d-glucosone 2 (d-arabino-hexos-2-ulose) in aqueous phosphate buffer at pH 7.5 and 37 °C have been investigated by 13C and 1H NMR spectroscopy with the use of singly and doubly 13C-labeled isotopomers of 2. Unlike its 3-deoxy analogue, 3-deoxy-d-glucosone (3-deoxy-d-erythro-hexos-2-ulose) (1), 2 does not degrade via a 1,2-hydrogen shift mechanism but instead initially undergoes C1-C2 bond cleavage to yield d-ribulose 3 and formate. The latter bond cleavage occurs via a 1,3-dicarbonyl intermediate initially produced by enolization at C3 of 2. However, a careful monitoring of the fates of the sketetal carbons of 2 during its conversion to 3 revealed unexpectedly that C1-C2 bond cleavage is accompanied by C1-C2 transposition in about 1 out of every 10 transformations. Furthermore, the degradation of 2 is catalyzed by inorganic phosphate (Pi), and by the Pi-surrogate, arsenate. C1-C2 transposition was also observed during the degradation of the C5 osone, d-xylosone (d-threo-pentose-2- ulose), showing that this transposition may be a common feature in the breakdown of 1,2-dicarbonyl sugars bearing an hydroxyl group at C3. Mechanisms involving the reversible formation of phosphate adducts to 2 are proposed to explain the mode of Pi catalysis and the C1-C2 transposition. These findings suggest that the breakdown of 2 in vivo is probably catalyzed by Pi and likely involves C1-C2 transposition.
