Check Digit Verification of cas no

The CAS Registry Mumber 1245833-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,8,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1245833-40:
(9*1)+(8*2)+(7*4)+(6*5)+(5*8)+(4*3)+(3*3)+(2*4)+(1*0)=152
152 % 10 = 2
So 1245833-40-2 is a valid CAS Registry Number.

Rhodium(I)-catalyzed [3+2+2]-cyclization of alkenyl Fischer carbene complexes with methyl buta-2,3-dienoate

Barluenga, José,Vicente, Rubén,López, Luis A.,Tomás, Miguel

, p. 6335 - 6339 (2010)

A variety of alkenyl chromium Fischer carbene complexes react with methyl buta-2,3-dienoate in the presence of a rhodium catalyst to afford substituted cycloheptene derivatives 7, along with minor amounts of cyclopentene derivatives 6. Through this [3+2+2]-cyclization two allene units and one alkenyl carbene ligand are assembled in a selective manner.
