Check Digit Verification of cas no

The CAS Registry Mumber 189324-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,2 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189324-80:
(8*1)+(7*8)+(6*9)+(5*3)+(4*2)+(3*4)+(2*8)+(1*0)=169
169 % 10 = 9
So 189324-80-9 is a valid CAS Registry Number.

Simple syntheses of L-fucopyranose and fucosidase inhibitors utilizing the highly stereoselective methylation of an arabinofuranoside 5-urose derivative

Takahashi, Shunya,Kuzuhara, Hiroyoshi

, p. 607 - 612 (2007/10/03)

The simple syntheses of L-fucopyranose 1 and its three analogues 2-4 are described. A key reaction is a stereocontrolled elongation by one carbon unit at the side chain of an α-D-arabino-pentodialdo-1,4-furanoside 9 with MeMgI-ZnCl2 or Me3Al. Diastereofacial selectivities of more than 92% were achieved.
