122075-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122075-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,7 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122075-43:
(8*1)+(7*2)+(6*2)+(5*0)+(4*7)+(3*5)+(2*4)+(1*3)=88
88 % 10 = 8
So 122075-43-8 is a valid CAS Registry Number.

CONJUGATE ADDITIONS ON α-PHENYLTHIO-α,β-UNSATURATED OXAZOLINES. NOVEL SYNTHESIS OF 3,4-DISUBSTITUTED COUMARINS.
Clinet, J. C.
, p. 5901 - 5904 (2007/10/02)
Nucleophilic addition of organolithium, Grignard and hydride reagents to α-phenylthio-α,β-unsaturated oxazolines is regioselective and occurs in a 1,4-fashion.This leads to a novel, versatile synthesis of polysubstituted coumarins.
