118467-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118467-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,6 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118467-19:
(8*1)+(7*1)+(6*8)+(5*4)+(4*6)+(3*7)+(2*1)+(1*9)=139
139 % 10 = 9
So 118467-19-9 is a valid CAS Registry Number.

SYNTHESIS OF CYCLIC α'α'-DISUBSTITUTED-α-ALKYL-γ-HYDROXY-α,β-ENONES FROM α-PHENYLTHIO-α,β-ENONES
Jarowcki, Krzysztof
, p. 607 - 612 (2007/10/02)
Key reactions in a "two pot" synthesis of cyclic γ-hydroxy-α,β-enones (6) from α-phenylthioenones (1) are regioselective α-alkylation of the α-phenylthioenones (1) and sigmatropic rearrangement of the sulphoxide (3).
