161087-62-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161087-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,0,8 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161087-62:
(8*1)+(7*6)+(6*1)+(5*0)+(4*8)+(3*7)+(2*6)+(1*2)=123
123 % 10 = 3
So 161087-62-3 is a valid CAS Registry Number.

AN APPROACH TO A 1-OXACEPHEM SKELETON FROM D-GALACTOSE
Belzecki, Czeslaw,Chmielewski, Marek
, p. 1103 - 1114 (2007/10/02)
2,4,6-Tri-O-benzyl-D-galactal (1) was transformed into a 1-oxacephem skeleton.The sequence of reaction involved: cycloaddition, N-alkylation, glycolic cleavage of the vic-diol grouping, reduction of dialdehyde and cyclization to the title skeleton.
