Check Digit Verification of cas no

The CAS Registry Mumber 143585-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143585-30:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*5)+(2*3)+(1*0)=132
132 % 10 = 2
So 143585-30-2 is a valid CAS Registry Number.

Chelate-Controlled Mukaiyama Reactions with Chiral β-Formyl Esters

Angert, Hubert,Kunz, Thomas,Reissig, Hans-Ulrich

, p. 5681 - 5690 (2007/10/02)

Additions of silyl enol ethers 3, 6, and 8 to chiral β-formyl esters 1 in the presence of TiCl4 provide trans-γ-lactones 4, 7, and 9 in high yield and with good to excellent diastereofacial selectivity.This high trans-preferrence is due to effective chelate-control involving seven-membered ring 1-TiCl4 complexes.
