20708-10-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20708-10-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,0 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20708-10:
(7*2)+(6*0)+(5*7)+(4*0)+(3*8)+(2*1)+(1*0)=75
75 % 10 = 5
So 20708-10-5 is a valid CAS Registry Number.

Lewis base-catalyzed divergent isomerizations of 5-hydroxyl-2,3-dienoate
Dong, Wei,Hu, Pengfei,Hu, Jian,Tong, Xiaofeng
supporting information, p. 1682 - 1685 (2014/03/21)
A divergent isomerization of 5-hydroxyl-2,3-dienoate 1 catalyzed by Lewis base has been developed, the phosphine catalyst leads to 5-oxohex-2(3)-enoates 2 while DABCO catalyst affords 3-ethoxy α,β-unsaturated lactone 3.
