121900-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121900-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,0 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121900-93:
(8*1)+(7*2)+(6*1)+(5*9)+(4*0)+(3*0)+(2*9)+(1*3)=94
94 % 10 = 4
So 121900-93-4 is a valid CAS Registry Number.

SYNTHESIS OF γ-LACTONES FROM ALKENES EMPLOYING p-METHOXYBENZYL CHLORIDE AS (1+)CH2-CO2(1-) EQUIVALENT
Baeuml, Englbert,Tscheschlok, Kai,Pock, Rudolf,Mayr, Herbert
, p. 6925 - 6926 (1988)
The ZnCl2 catalyzed reaction of p-methoxybenzyl chloride with alkenes yields the 1:1 addition products 3, which are converted into the γ-lactones 4 via Ru(VIII) catalyzed oxidative degradation of the aromatic ring.
