126892-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126892-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,9 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126892-11:
(8*1)+(7*2)+(6*6)+(5*8)+(4*9)+(3*2)+(2*1)+(1*1)=143
143 % 10 = 3
So 126892-11-3 is a valid CAS Registry Number.

ENANTIOCONVERGENT SYNTHESIS OF (-)-α-CUPARENONE INVOLVING CHIRAL INVERSION OF A KETONE INTERMEDIATE
Gharpure, Milind M.,Rao, A.S.
, p. 1813 - 1824 (2007/10/02)
The acid (-)-2 was converted to the ketone (-)-6.Unsaturated ketone (+)-14 was synthesised from (-)-6.The ketone (+)-7 prepared from the acid (+)-3 on 1,2-ketone transposition, furnished the optical antipode (-)-6.
