100420-14-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100420-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,2 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100420-14:
(8*1)+(7*0)+(6*0)+(5*4)+(4*2)+(3*0)+(2*1)+(1*4)=42
42 % 10 = 2
So 100420-14-2 is a valid CAS Registry Number.

SYNTHESIS OF PHENOLS BY POLYKETIDE CONDENSATION AND AN EFFICIENT SYNTHESIS OF 3,5-DIOXOALKANOATES FROM AMIDES
Yamaguchi, Masahiko,Shibato, Keisuke,Hirao, Ichiro
, p. 1145 - 1148 (1985)
Several phenols were synthesized from dimethyl β,β',δ,δ'-tetraoxoalkanedioates, which were prepared by the condensation of methyl acetoacetate dianion with N,N,N',N'-tetramethyl-alkanediamides in the presence of BF3*OEt2.
