109915-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109915-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,1 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109915-85:
(8*1)+(7*0)+(6*9)+(5*9)+(4*1)+(3*5)+(2*8)+(1*5)=147
147 % 10 = 7
So 109915-85-7 is a valid CAS Registry Number.

Facile synthesis of 3,4-dihydro-α-pyrones via Michael reaction-O-acylation sequences
Kobayashi, Shu,Moriwaki, Mitsuhiro
, p. 551 - 552 (2007/10/03)
3,4-Dihydro-α-pyrones were prepared in excellent yields with high stereoselectivities by the trityl salt-catalyzed Michael reaction and sequential intramolecular O-acylation of the intermediary silyl enol ethers using a mercury (II) salt (one-pot reaction
