1202397-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202397-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,3,9 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1202397-18:
(9*1)+(8*2)+(7*0)+(6*2)+(5*3)+(4*9)+(3*7)+(2*1)+(1*8)=119
119 % 10 = 9
So 1202397-18-9 is a valid CAS Registry Number.

Iridium-catalyzed, regio- and enantioselective allylic substitution with aromatic and aliphatic sulfinates
Ueda, Mitsuhiro,Hartwig, John F.
, p. 92 - 94 (2010)
"Chemical Equation Presented" The iridium-catalyzed allylation of sodium sulfinate to form branched allylic sulfones is reported. The reactions between various sodium sulfinates and achiral allylic carbonates occur in good yields, with high selectivity fo
