Check Digit Verification of cas no

The CAS Registry Mumber 159853-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,5 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159853-70:
(8*1)+(7*5)+(6*9)+(5*8)+(4*5)+(3*3)+(2*7)+(1*0)=180
180 % 10 = 0
So 159853-70-0 is a valid CAS Registry Number.

Synthesis of novel bis(benzoxazole) derivatives by tandem Claisen rearrangement and their fluorescence behavior

Koyama, Emiko,Yang, Gang,Tsuzuki, Seiji,Hiratani, Kazuhisa

, p. 1996 - 2006 (2007/10/03)

Novel bis(benzoxazole) derivatives were easily synthesized from isobutenyl bis(amide-ether)s by tandem Claisen rearrangement and subsequent intramolecular cyclization of the amide-phenol intermediates. The yields of the bis(benzoxazole)s depended on wheth

New Synthesis of Macrocyclic Crown-Formazans from Pyruvic Acid Derivatives

Ibrahim, Yehia A.,Elwahy, Ahmed H. M.,Abbas, Ashraf A.

, p. 11489 - 11498 (2007/10/02)

The macrocyclic crown-formazans 7a-c, 12a-g were prepared by the azo-coupling of the appropriate bis-diazonium salts 4a-c with pyruvic acid and arylpyruvic acids 8a-c.The ready accessability of the latters offers an easy access towards 1,5-symmetrically d
