Check Digit Verification of cas no

The CAS Registry Mumber 1262623-27-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,6,2 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1262623-27:
(9*1)+(8*2)+(7*6)+(6*2)+(5*6)+(4*2)+(3*3)+(2*2)+(1*7)=137
137 % 10 = 7
So 1262623-27-7 is a valid CAS Registry Number.

Cobalt Catalyst-Controlled Selective Dioxygenation of Styrenes Using N-Hydroxyphthalimide with Molecular Oxygen

Hao, Xiaosong,Ji, Huihui,Zhan, Hongju,Zhang, Qian,Li, Dong

supporting information, p. 193 - 199 (2021/10/14)

A cobalt-catalyzed selective dioxygenation of styrenes with N-hydroxyphthalimide (NHPI) was developed using molecular oxygen as the terminal oxidant. Alcohol and ketone products can be selectively formed from identical substrates by catalyst control. The reaction was applicable to a broad range of styrenes and exhibited good functional group tolerance. It provided a method for preparation of 1,2-diol or α-hydroxyketone derivatives. (Figure presented.).

Visible-light- induced aerobic dioxygenation of styrenes under metal- and additive-free ambient conditions

Samanta, Supravat,Ravi, Chitrakar,Joshi, Abhisek,Pappula, Venkatanarayana,Adimurthy, Subbarayappa

supporting information, p. 721 - 725 (2017/03/31)

Visible light promoted hydroperoxidation of styrenes using hydroxylamine and molecular oxygen from air under metal-free and additive-free conditions at room temperature is described. Hydroperoxides were further converted into corresponding hydroxy compoun

Copper(II)-catalyzed direct dioxygenation of alkenes with air and n -hydroxyphthalimide: Synthesis of β-keto- N -alkoxyphthalimides

Bag, Raghunath,Sar, Dinabandhu,Punniyamurthy, Tharmalingam

supporting information, p. 2010 - 2013 (2015/04/27)

Copper(II)-catalyzed direct dioxygenation of alkenes using air and a simple N-hydroxyphthalimide leading to β-keto-N-alkoxyphthalimides has been developed. The reaction system is mild, efficient, and effective at room temperature with broad substrate scope and substantial steric hindrance. The radical-trapping and 18O-labeling experiments have been demonstrated.
