Check Digit Verification of cas no

The CAS Registry Mumber 1258930-42-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,9,3 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1258930-42:
(9*1)+(8*2)+(7*5)+(6*8)+(5*9)+(4*3)+(3*0)+(2*4)+(1*2)=175
175 % 10 = 5
So 1258930-42-5 is a valid CAS Registry Number.

A facile and practical solvent-free one-pot synthesis of (Z)-4-methylene-3-selenaquinoline derivatives from o-ethynylanilines and isoselenocyanates

Sashida, Haruki,Pan, Chao,Kaname, Mamoru,Minoura, Mao

experimental part, p. 3091 - 3096 (2010/10/21)

Heating of o-ethynylanilines with isoselenocyanates directly resulted in the 6-exo-dig mode ring-closure reaction of the adducts to give the (Z)-2-imino-4-methylene-3-selenaquinolines in moderate to good yields. Based on this convenient, solvent-free, catalyst-free method, several 3-selenaquinoline derivatives (3,1-benzoselenazines) were easily obtained in one pot. Successful application of the microwave-assisted synthesis of these compounds was also investigated. Georg Thieme Verlag Stuttgart - New York.
