Check Digit Verification of cas no

The CAS Registry Mumber 443752-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,7,5 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 443752-42:
(8*4)+(7*4)+(6*3)+(5*7)+(4*5)+(3*2)+(2*4)+(1*2)=149
149 % 10 = 9
So 443752-42-9 is a valid CAS Registry Number.

Highly stereoselective syntheses of all 1,2,3-Me,OH,Me triads via asymmetric hydrogenation reactions

Zhu, Ye,Burgess, Kevin

, p. 107 - 115 (2013/03/14)

Iridium-catalyzed asymmetric hydrogenations of chiral alkenes were used to access four pivotal α,ω-functionalized chirons, that contain widely occurring stereochemical 1,2,3-Me,OH,Me motifs. A chiral analogue of Crabtree's catalyst was used in key hydrogenation steps to form these motifs with high stereochemical purities. An application of one of these chirons is illustrated here with a synthesis of (-)-invictolide. Copyright

Studies directed toward the synthesis of the C15-C21 fragment of (-)-discodermolide

Chakraborty, Tushar K.,Laxman, Pasunoori

, p. 543 - 545 (2007/10/03)

A novel method developed by us recently for the synthesis of chiral 2-methyl-1,3-diols by radical-mediated diastereoselective opening of trisubstituted epoxy alcohols at the more substituted carbon serves as the key step in our studies directed toward the
