Check Digit Verification of cas no
The CAS Registry Mumber 144404-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,0 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144404-96:
(8*1)+(7*4)+(6*4)+(5*4)+(4*0)+(3*4)+(2*9)+(1*6)=116
116 % 10 = 6
So 144404-96-6 is a valid CAS Registry Number.

Distinction of Diastereofaces at the α-Position of Chiral Cyclic Acetals
Tanaka, Naoki,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 1075 - 1086 (2007/10/02)
Key words: chiral acetal; asymmetric 1,2-addition; asymmetric 1,4-addition; C2 symmetry; determination of optical purity; chiral carboxylic acid Asymmetric 1,2- and 1,4-additions to substrates with an acetal as a chiral auxiliary have been studied.Among the tested substrates, C2-symmetrical 5c was most effective for 1,2-addition with MeTi(O-iPr)3.Furthermore, C2-symmetrical carbinol 5b has been found to be a potent 1H-NMR reagent for determination of optical purity of carboxylic acids with a chiral center at the α-position.
