Check Digit Verification of cas no

The CAS Registry Mumber 74385-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,8 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74385-62:
(7*7)+(6*4)+(5*3)+(4*8)+(3*5)+(2*6)+(1*2)=149
149 % 10 = 9
So 74385-62-9 is a valid CAS Registry Number.

Stereochemistry of Allenic Compounds. 3. Geometrical Deformations of the Propadiene Unit in Cyclic Allenes

Luche, Jean-Louis,Damiano, Jean-Claude,Cohen-Addad, Claudine

, p. 5370 - 5374 (1980)

The structures of phenylurethane derivatives of cyclic allenes 7 were investigated by X-ray analysis. 7a and 7c form analogous pairs of homochiral chains and spontaneous resolution has been observed for 7b and 7c.Bending and twisting of the cumulated system were evidenced.Deviations from the ideal geometry, which were predicted by theoretical calculations, should be taken into account in the interpretation of the chiroptical properties of allenic compounds.
