Check Digit Verification of cas no

The CAS Registry Mumber 76870-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76870-57:
(7*7)+(6*6)+(5*8)+(4*7)+(3*0)+(2*5)+(1*7)=170
170 % 10 = 0
So 76870-57-0 is a valid CAS Registry Number.

Double heteroannulation of S,N-acetals: A facile access to quinolone derivatives

Janni, Manojkumar,Arora, Sahil,Peruncheralathan

, p. 8781 - 8788 (2016/10/03)

A rapid construction of quinolone fused heterocycles from single S,N-acetal precursors via double heteroannulation is described. The base, radical and metal-mediated reactions can control the C-N, C-S and C-O bond formations of the S,N-acetal with high chemoselectivity.

Synthesis of Benzofuranes by Cyclodehydrogenation of Phenylmalonyl Heterocyclic Compounds

Stadlbauer, Wolfgang,Schmut, Otto,Kappe, Thomas

, p. 1005 - 1014 (2007/10/02)

Phenylmalonyl heterocyclic compounds such as the quinolones 1a-c or 3, benzoquinolizinones 6a, b and the phenalenones 8a, b can be converted to benzofuranes (2a-c, 7a, b and 9a, b) by cyclodehydrogenation with Pd/C in boiling diphenyl ether. 2-Phenylchinc
