Check Digit Verification of cas no

The CAS Registry Mumber 338744-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,7,4 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 338744-52:
(8*3)+(7*3)+(6*8)+(5*7)+(4*4)+(3*4)+(2*5)+(1*2)=168
168 % 10 = 8
So 338744-52-8 is a valid CAS Registry Number.

A highly convergent synthesis of a complex oligosaccharide derived from group B type III Streptococcus

Demchenko,Boons

, p. 2547 - 2554 (2001)

An efficient synthesis of a heptasaccharide derived from group B type III Streptococcus carrying an artificial spacer (1) is described. Rapid assembly of a protected heptasaccharide (16a) is accomplished from readily available building blocks 2-5 without a single protecting group manipulation between glycosylation steps. The synthetic strategy may be applied to the assembly of other branched complex oligosaccharides. The deprotected heptasaccharide 1 was coupled to a poly[N-(acryloyloxy)succinimide, and the resulting material will be used for the development of an ELISA assay to detect antibodies against GBS, type III in pregnant women.
