Check Digit Verification of cas no

The CAS Registry Mumber 191729-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,7,2 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 191729-47:
(8*1)+(7*9)+(6*1)+(5*7)+(4*2)+(3*9)+(2*4)+(1*7)=162
162 % 10 = 2
So 191729-47-2 is a valid CAS Registry Number.

Anomalous Horner-Wadsworth-Emmons reactions on 3,4-enuloses

Moradei, Oscar M.,Du Mortier, Cecile M.,Cirelli, Alicia Fernandez

, p. 7397 - 7402 (1997)

Pyranosic enuloses were subjected to Horner-Wadsworth-Emmons (HWE) conditions using the enolate of dimethyl(methoxycarbonyl)methyl phosphonate and its ethyl analogue. 3-O-Phosphorylation of the products as well as an unusual stereospecificity were observe
