1191256-36-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191256-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,2,5 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1191256-36:
(9*1)+(8*1)+(7*9)+(6*1)+(5*2)+(4*5)+(3*6)+(2*3)+(1*6)=146
146 % 10 = 6
So 1191256-36-6 is a valid CAS Registry Number.

The reaction of terminal alkynes with PhI(OAc)2: a convenient procedure for the preparation of α-acyloxy ketones
Mo, Dong-Liang,Dai, Li-Xin,Hou, Xue-Long
, p. 5578 - 5581 (2009)
Treatment of terminal alkynes with PhI(OAc)2 in different acids at 70 °C provided the corresponding α-acyloxy ketones in good to excellent yields. A plausible mechanism has been proposed based on the experimental results.
