232266-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 232266-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,2,2,6 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 232266-98:
(8*2)+(7*3)+(6*2)+(5*2)+(4*6)+(3*6)+(2*9)+(1*8)=127
127 % 10 = 7
So 232266-98-7 is a valid CAS Registry Number.

Synthesis of Butenolides via a Horner-Wadsworth-Emmons Cascading Dimerization Reaction
Everson, Jack,Kiefel, Milton J.
, p. 15226 - 15235 (2019/11/21)
The efficient synthesis of a range of structurally related butenolides has been observed while we were exploring the substrate-scope of a Horner-Wadsworth-Emmons (HWE) reaction. While aliphatic aldehydes gave the expected HWE product, aromatic aldehydes f
