133285-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133285-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133285-91:
(8*1)+(7*3)+(6*3)+(5*2)+(4*8)+(3*5)+(2*9)+(1*1)=123
123 % 10 = 3
So 133285-91-3 is a valid CAS Registry Number.

Palladium-catalyzed carbonyl allylation by 2-(hydroxymethyl)acrylate derivatives: Synthesis of α-methylene-γ-butyrolactones
Masuyama,Nimura,Kurusu
, p. 225 - 228 (2007/10/02)
Ethyl 2-(hydroxymethyl)acrylate derivatives serve as reagents for 2-ethoxycarnonylallylation of carbonyl compounds using PdCl2(PhCN)2-SnCl2 system to produce α-methylene-γ-butyrolactones diastereoselectively.
