Check Digit Verification of cas no

The CAS Registry Mumber 1346936-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,9,3 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1346936-73:
(9*1)+(8*3)+(7*4)+(6*6)+(5*9)+(4*3)+(3*6)+(2*7)+(1*3)=189
189 % 10 = 9
So 1346936-73-9 is a valid CAS Registry Number.

Efficient Synthesis of Chromenes from Vinyl o -Quinone Methides via a Bronsted Acid Catalyzed Electrocyclization Process

Liu, Si-Jia,Jiang, Xiao-Li,Wu, Shu-Fang,Tu, Man-Su,Mei, Guang-Jian,Shi, Feng

, p. 2416 - 2422 (2018)

An efficient approach for the synthesis of chromene derivatives from vinyl o -quinone methides was established via a Bronsted acid catalyzed electrocyclization. By using this methodology, a series of structurally diversified chromenes was synthesized in a highly atom-economic and environmentally benign manner with generally good to excellent yields (up to 98% yield). This reaction will not only provide an efficient method for the construction of chromene scaffolds, but also enrich the research area of o -quinone methides.
