Check Digit Verification of cas no

The CAS Registry Mumber 1408280-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,8,2,8 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1408280-75:
(9*1)+(8*4)+(7*0)+(6*8)+(5*2)+(4*8)+(3*0)+(2*7)+(1*5)=150
150 % 10 = 0
So 1408280-75-0 is a valid CAS Registry Number.

Base-catalyzed efficient tandem [3 + 3] and [3 + 2 + 1] annulation-aerobic oxidative benzannulations

Diallo, Aboubacar,Zhao, Yu-Long,Wang, He,Li, Sha-Sha,Ren, Chuan-Qing,Liu, Qun

supporting information, p. 5776 - 5779 (2013/01/15)

An efficient synthesis of substituted benzenes via a base-catalyzed [3 + 3] aerobic oxidative aromatization of α,β-unsaturated carbonyl compounds with dimethyl glutaconate was reported. All the reactions were carried out under mild, metal-free conditions to afford the products in high to excellent yields with molecular oxygen as the sole oxidant and water as the sole byproduct. Furthermore, a more convenient tandem [3 + 2 + 1] aerobic oxidative aromatization reaction was developed through the in situ generation of the α,β-unsaturated carbonyl compounds from aldehydes and ketones.
