Check Digit Verification of cas no

The CAS Registry Mumber 149331-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,3 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149331-12:
(8*1)+(7*4)+(6*9)+(5*3)+(4*3)+(3*1)+(2*1)+(1*2)=124
124 % 10 = 4
So 149331-12-4 is a valid CAS Registry Number.

Regioselectivity of the insertion reactions of some aromatic diazo compound complexes with cyclomaltoheptaose

Smith,Forrest,Williams Jr.,Cabell,Acquavella,Abelt

, p. 289 - 297 (2007/10/02)

Pyrolysis of solid complexes of aromatic diazo compounds with cyclomaltoheptaose (β-cyclodextrin) yields ether derivatives via insertion of carbene into hydroxyl groups. The distribution of the 2-, 3-, and 6-O-isomers indicates that the regioselectivity is moderate. The guest geometry is not as important as its size in determining the ratios of regioisomers. The origins of the regioselectivity are discussed.
