Check Digit Verification of cas no

The CAS Registry Mumber 103150-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103150-22:
(8*1)+(7*0)+(6*3)+(5*1)+(4*5)+(3*0)+(2*2)+(1*2)=57
57 % 10 = 7
So 103150-22-7 is a valid CAS Registry Number.

Allylic Displacements and a Novel Ester-Ether Interchange in Fused Cyclobutanones

Hassner, Alfred,Dillon, John

, p. 3315 - 3319 (2007/10/02)

Chlorophenylcyclobutanone 11, prepared by chlorophenylketene addition to cyclohexene, reacts readily with simple and hindered carboxylic acids in a cine substitution to produce keto esters 14.The acyloxy and phenyl substituents in 14c are shown by X-ray diffraction to be cis oriented; nevertheless 14 reacts with NaOMe at 20 deg C by an unusual ester-ether interchange to produce 15 and the released carboxylate RCO2-.These reactions apparently proceed via an oxyallyl cation intermediate.The behaviors of related cyclobutanones 4, 6, and 11 with methoxide are contrasted.
