154230-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154230-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,3 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154230-50:
(8*1)+(7*5)+(6*4)+(5*2)+(4*3)+(3*0)+(2*5)+(1*0)=99
99 % 10 = 9
So 154230-50-9 is a valid CAS Registry Number.

Synthesis of optically active 4-benzyloxymethyl- and 4-(4-methoxyphenoxy)methylbuten-2-olides via lipase-mediated resolution
Takano,Setoh,Yamada,Ogasawara
, p. 1253 - 1256 (1993)
A new preparation of optically active 4-benzyloxymethyl- and 4-(4-methoxyphenoxy)methylbuten-2-olides has been developed by employing lipase-mediated resolution and palladium-mediated carbomethoxylation as key steps.
