142074-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142074-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,7 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142074-30:
(8*1)+(7*4)+(6*2)+(5*0)+(4*7)+(3*4)+(2*3)+(1*0)=94
94 % 10 = 4
So 142074-30-4 is a valid CAS Registry Number.

Intramolecular Oxidative Coupling of Aromatic Compounds. IV. Oxidation of Non-Phenolic Substrates
Krauss, Adrian S.,Taylor, Walter C.
, p. 935 - 939 (2007/10/02)
Intramolecular non-phenolic coupling of (2RS,3SR)-1,4-bis(4-benzyloxy-3,5-dimethoxyphenyl)-2,3-dimethylbutan-1-one (6) failed.Oxidation of the derived butane (9) gave the aryltetralin (14) in low yield.
