136758-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136758-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,5 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136758-66:
(8*1)+(7*3)+(6*6)+(5*7)+(4*5)+(3*8)+(2*6)+(1*6)=162
162 % 10 = 2
So 136758-66-2 is a valid CAS Registry Number.

A stereoselective synthetic route to cis-2,5-disubstituted tetrahydrofurans
Kang,Hwang,Kim,Lim
, p. 4015 - 4018 (2007/10/02)
An efficient stereocontrolled synthesis of cis-2,5-disubstituted tetrahydrofurans from triethylsilyl ethers of trans-4-phenyl-3-buten-1-ol derivatives 19-24 was developed by using phenylselenyl chloride in the presence of potassium carbonate in acetonitri
