41500-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41500-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,5,0 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 41500-03:
(7*4)+(6*1)+(5*5)+(4*0)+(3*0)+(2*0)+(1*3)=62
62 % 10 = 2
So 41500-03-2 is a valid CAS Registry Number.

Generation and C-Ethoxycarbonylation of Enolates Using Ultrasound
Palominos, Mario A.,Rodriguez, Robinson,Vega, Juan C.
, p. 1251 - 1254 (1986)
O-Ethyl 3-oxothioesters were obtained in good yields by reaction of O,O-diethyl trithiodicarbonate with enolate from ketones and NaH in tetrahydrofuran.The enolate formation and thioacylation were performed under ultrasonic irradiation.
