116546-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116546-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,4 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116546-81:
(8*1)+(7*1)+(6*6)+(5*5)+(4*4)+(3*6)+(2*8)+(1*1)=127
127 % 10 = 7
So 116546-81-7 is a valid CAS Registry Number.

ALDOL CONDENSATIONS OF CHIRAL ETHYLKETONES: CONTROL BY CHIRAL BORON REAGENTS.
Paterson, Ian,Lister, Anne M.
, p. 585 - 588 (2007/10/02)
The chiral reagents (+)- and (-)-(Ipc)2BOTf, in the presence of Et3N, are used to control the aldol condensation reactions of chiral ethylketone 5 with prochiral aldehydes.The SS isomer, 6 or 8, or SA isomer, 7 or 9, is then formed in >99 percentee and wi
