127903-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127903-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127903-41:
(8*1)+(7*2)+(6*7)+(5*9)+(4*0)+(3*3)+(2*4)+(1*1)=127
127 % 10 = 7
So 127903-41-7 is a valid CAS Registry Number.

Conjugate addition of lithium diorganocuprate reagents to the enol tosylate of a 1,2-diketone
Charonnat,Mitchell,Keogh
, p. 315 - 318 (2007/10/02)
The conjugate addition of lithium diorganocuprate reagents to the enol tosylate of 1,2-cyclohexanedione has been investigated. The intermediate enolates eliminate para-toluenesulfinate ion to generate the alkylated 1,2-dicarbonyl system.
