Check Digit Verification of cas no

The CAS Registry Mumber 1417175-87-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,1,7 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1417175-87:
(9*1)+(8*4)+(7*1)+(6*7)+(5*1)+(4*7)+(3*5)+(2*8)+(1*7)=161
161 % 10 = 1
So 1417175-87-1 is a valid CAS Registry Number.

Enantioselective syn and anti homocrotylation of aldehydes: Application to the formal synthesis of spongidepsin

Lin, Hongkun,Tian, Leiming,Krauss, Isaac J.

, p. 13176 - 13182 (2015)

Whereas crotylboration has been a useful method for synthesis of stereochemically complex products, we have shown that homocrotylboration can be achieved with cyclopropanated crotylation reagents, and that the stereoselectivity of the reaction can be predicted by analogous models. This paper presents a full account of this work, including the first examples of asymmetric anti homocrotylation. The scope of this reaction is demonstrated with highly enantioselective homocrotylation of both aliphatic and aromatic aldehydes, as well as double diastereoselection studies. An application of the synthesis of the marine natural product spongidepsin is presented, as well as streamlined syntheses of homocrotylation reagents.
