Check Digit Verification of cas no

The CAS Registry Mumber 137934-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137934-85:
(8*1)+(7*3)+(6*7)+(5*9)+(4*3)+(3*4)+(2*8)+(1*5)=161
161 % 10 = 1
So 137934-85-1 is a valid CAS Registry Number.

Formation of isoxazolines N-oxides and dihydrofurans from a cyclocondensation between bromo or chloromalonate carbanion and Michael acceptors

Menn, J. C. Le,Sarrazin, J.,Tallec, A.

, p. 562 - 565 (2007/10/02)

Heterocyclic compounds are prepared by a cyclocondensation reaction between halomalonate carbanion and Michael acceptors : α-nitroalkenes lead to isoxazolines N-oxides and α,β-unsaturated carbonyl derivatives to dihydrofurans.Formation of the carbanion results from deprotonation of monohalomalonates with powdered potassium carbonate in THF; as a rule; chloromalonate affords better yields than bromomalonate.Key Words: halomalonate carbanions / electrophilic alkenes / dihydrofurans / isoxazolines N-oxide
