466680-60-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 466680-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,6,6,8 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 466680-60:
(8*4)+(7*6)+(6*6)+(5*6)+(4*8)+(3*0)+(2*6)+(1*0)=184
184 % 10 = 4
So 466680-60-4 is a valid CAS Registry Number.

Chemical transformation of lactose into 4-O-beta-D-galactopyranosyl-D-glucuronic acid (pseudolactobiouronic acid) and some derivatives thereof.

Attolino, Emanuele,Catelani, Giorgio,D'Andrea, Felicia,Puccioni, Leonardo

, p. 991 - 996 (2002)

The selective oxidation of the primary alcoholic function of the reducing unit of lactose was achieved in good overall yield (67%) starting from 2',6'-di-O-benzyl-2,3:3',4'-di-O-isopropylidenelactose dimethyl acetal (1) through a simple multi-step procedure based on the selective acetylation of OH-5 of 1 (methoxyisopropylation, acetylation, de-methoxyisopropylation) followed by a two-step oxidation at C-6 (TPAP-NMO then TEMPO-NaOCl) and finally, complete removal of the protecting groups.
