Check Digit Verification of cas no

The CAS Registry Mumber 1520087-46-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,2,0,0,8 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1520087-46:
(9*1)+(8*5)+(7*2)+(6*0)+(5*0)+(4*8)+(3*7)+(2*4)+(1*6)=130
130 % 10 = 0
So 1520087-46-0 is a valid CAS Registry Number.

Ru(II)-Catalyzed C-H Activation and Annulation Reaction via Carbon-Carbon Triple Bond Cleavage

Prakash, Rashmi,Bora, Bidisha R.,Boruah, Romesh C.,Gogoi, Sanjib

supporting information, p. 2297 - 2300 (2018/04/30)

An unprecedented Ru(II)-catalyzed C-H activation and annulation reaction, which proceeds via C-C triple bond cleavage, is reported. This reaction of 2-phenyldihydrophthalazinediones with alkynes, which works most efficiently in the presence of bidented ligand 1,3-bis(diphenylphosphino)propane, affords good yields of substituted quinazolines.

Nickel-catalyzed Kumada Cross-coupling Reaction for the Synthesis of 2,4-Diarylquinazolines

Ye, Xinglin,Yuan, Zhihan,Zhou, Yirong,Yang, Qin,Xie, Yepeng,Deng, Zhihong,Peng, Yiyuan

supporting information, p. 1956 - 1962 (2016/11/24)

A series of 2,4-diarylquinazolines have been successfully synthesized via the Ni-catalyzed cross-coupling reaction of quinazoline-4-tosylates and aryl Grignard reagents, which provided alternative straightforward approaches for the introduction of aryl groups to quinazolines at C-4 position.
