4412-93-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4412-93-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,1 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4412-93:
(6*4)+(5*4)+(4*1)+(3*2)+(2*9)+(1*3)=75
75 % 10 = 5
So 4412-93-5 is a valid CAS Registry Number.

Efficient and convenient synthesis of angular furanocoumarins from hydroxycoumarins
Harayama, Takashi,Nishita, Yoshitaka
, p. 1986 - 1988 (2007/10/03)
Angular furanocoumarins (1) were synthesized via sequential reactions of vinylation of halo-hydroxycoumarins (5 or 6) with chlorodimethylvinylsilane (8) and Pd catalyst, oxidation of Tl(NO3)3 in methanol, and treatment with acid.
