Check Digit Verification of cas no

The CAS Registry Mumber 244094-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,0,9 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 244094-95:
(8*2)+(7*4)+(6*4)+(5*0)+(4*9)+(3*4)+(2*9)+(1*5)=139
139 % 10 = 9
So 244094-95-9 is a valid CAS Registry Number.

Dibutyl tin oxide mediated, regioselective alkylation and acylation of siloxane protected glycopyranosides

Ziegler, Thomas,Dettmann, Ralf,Grabowski, Jaroslaw

, p. 1661 - 1665 (1999)

Treatment of alkyl and aryl 4,6-O-(1,1,3,3-tetraisopropyl-1,3- disiloxane-1,3-diyl)-D-glycopyranosides 2 with dibutyltin oxide followed by benzoyl chloride, benzyl bromide and allyl bromide afforded regioselectively the corresponding mono acylated and alkylated glycosides. The regioselective acylation of the stannylene intermediates is inverted as compared to the direct acylation of 2. Regioselective alkylations of 2 proceeded without affecting the siloxane residue.
