Check Digit Verification of cas no

The CAS Registry Mumber 17429-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,2 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17429-98:
(7*1)+(6*7)+(5*4)+(4*2)+(3*9)+(2*9)+(1*8)=130
130 % 10 = 0
So 17429-98-0 is a valid CAS Registry Number.

Selective derivatization of d-galactose towards a practical synthesis of C-6 l-fucose analogues

Pinto, Rui C.,Andrade, Marta M.,Barros, Maria Teresa

supporting information, p. 6633 - 6636,4 (2012/12/13)

Starting from d-galactose, a convenient protocol is described for the synthesis of l-fucose C-6 analogue, 2,3,4,5-tetra-O-acetyl-5-(1,3-dithiolan-2- yl)-l-galactopyranose, in an overall yield of 40% after 6 steps, making use of stable intermediates. A chemoselective protection/deprotection strategy was studied using TBDMS and TBDPS silyl ethers for protection of d-galactose primary hydroxyl group.
