Check Digit Verification of cas no

The CAS Registry Mumber 209113-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,1,1 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 209113-70:
(8*2)+(7*0)+(6*9)+(5*1)+(4*1)+(3*3)+(2*7)+(1*0)=102
102 % 10 = 2
So 209113-70-2 is a valid CAS Registry Number.

An expeditious route to the synthesis of kelampayosides A and B

Duynstee, Howard I.,De Koning, Martijn C.,Van der Marel, Gijs A.,Van Boom, Jacques H.

, p. 9881 - 9898 (2007/10/03)

Chemoselective NIS/cat. TfOH-mediated glycosylation of ethyl 2,3,4-tri- O-benzoyl-1-thio-β-D-glucopyranoside (13) with ethyl 2,3-di-O-acetyl-5-O- benzyl-1-thio-α/β-erythro-apiofuranoside (4a) gave direct 14 in an excellent yield. BF3·Et2O-catalysed condensation of the α- trichloroacetimidate 31, accessible in two steps from 14, with 3,4,5- trimethoxyphenol gave β-linked derivative 32 followed by deprotection gave Kelampayoside A. Protecting group manipulations of 32 and subsequent caffeoylation of resulting 36 followed by deprotection gave Kelampayoside B.
