113809-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113809-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113809-12:
(8*1)+(7*1)+(6*3)+(5*8)+(4*0)+(3*9)+(2*1)+(1*2)=104
104 % 10 = 4
So 113809-12-4 is a valid CAS Registry Number.

AN EFFICIENT ROUTE TO AMINOANTHRAQUINONES AND DERIVATIVES VIA A DIELS-ALDER REACTION.
Chigr, Mohamed,Fillion, Houda,Rougny, Annie
, p. 4529 - 4532 (2007/10/02)
Cycloadditions of (E)-1-N-carbobenzoxyamino-1,3-butadiene to naphtoquinones followed by aromatization of the adducts and deprotection of the amino group afford regioselective syntheses of -5 and -8 substituted aminoanthraquinones.
