Check Digit Verification of cas no

The CAS Registry Mumber 91860-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,6 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91860-98:
(7*9)+(6*1)+(5*8)+(4*6)+(3*0)+(2*9)+(1*8)=159
159 % 10 = 9
So 91860-98-9 is a valid CAS Registry Number.

ON THE COMMUNICATION OF CHIRALITY FROM FURANOSE AND PYRANOSE RINGS TO MONOSACCHARIDE SIDE CHAINS: ANOMALOUS RESULTS IN THE GLUCOSE SERIES

Danishefsky, Samuel J.,DeNinno, Michael P.,Phillips, Gary B.,Zelle, Robert E.

, p. 2809 - 2819 (2007/10/02)

The reactions of allyltrimethylsilane with dialdose derivatives occur, under catalysis by boron trifluoride etherate or titanium tetrachloride, with high stereoselectivity, thereby providing simple routes to the corresponding allyl carbinols.The sense of

Chelation-Controlled Facially Selective Cyclocondensation Reactions of Chiral Alkoxy Aldehydes: Syntheses of a Mouse Androgen and of a Carbon-Linked Disaccharide

Danishefsky, Samuel J.,Pearson, William H.,Harvey, Daniel F.,Maring, Clarence J.,Springer, James P.

, p. 1256 - 1268 (2007/10/02)

Magnesium bromide in tetrahydrofuran catalyzes the cycloaddition of a variety of chiral alkoxy aldehydes with activated butadienes.The stereochemistry of these products is such that they can be rationalized as arising from a reacting conformer in which th
