1033894-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1033894-70-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,8,9 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1033894-70:
(9*1)+(8*0)+(7*3)+(6*3)+(5*8)+(4*9)+(3*4)+(2*7)+(1*0)=150
150 % 10 = 0
So 1033894-70-0 is a valid CAS Registry Number.

A novel method for one-pot synthesis of furo[3,2-c]coumarin derivatives from 4-hydroxycoumarin and arylglyoxal under microwave irradiation
Chen, Zhiwei,Bi, Jianhao,Su, Weike
, p. 1845 - 1850 (2012/10/29)
A novel one-pot synthesis of furo[3,2-c]coumarins has been developed from readily available starting materials 4-hydroxycoumarin and arylglyoxal. This method is simple, rapid and good yielding.
