128050-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128050-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,5 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128050-69:
(8*1)+(7*2)+(6*8)+(5*0)+(4*5)+(3*0)+(2*6)+(1*9)=111
111 % 10 = 1
So 128050-69-1 is a valid CAS Registry Number.

An Unusual Cyclization of a Homoallyl Oxyacetic Acid Dianion
Raucher, Stanley,Gustavson, Linda M.,Stencamp, Ronald E.
, p. 2760 - 2762 (2007/10/02)
Treatment of the homoallyl oxyacetic acid 7 with excess LDA at -78 deg C followed by thermolysis at 185 deg C in HMPA provided the unusual cyclization product 8a.A single-crystal X-ray structure was obtined for the derivative 8c.
