Check Digit Verification of cas no

The CAS Registry Mumber 1243634-78-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,6,3 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1243634-78:
(9*1)+(8*2)+(7*4)+(6*3)+(5*6)+(4*3)+(3*4)+(2*7)+(1*8)=147
147 % 10 = 7
So 1243634-78-7 is a valid CAS Registry Number.

-

Page/Page column 93, (2012/02/02)

The invention provides novel cocaine analogs. The invention also provides a method of preparing cocaine analogs with control over the substituents installed at the C-1, C-2, C-3, C-4 and N-8 positions of the tropane bicyclic scaffold. The invention further provides a method of providing anesthesia to a subject in need thereof comprising administering to the subject a pharmaceutical composition comprising a compound of the invention. The invention also provides a method of blocking reuptake of a monoamine neurotransmitter in a subject in need thereof, to a subject in need thereof comprising administering to the subject a pharmaceutical composition comprising a compound of the invention.

Asymmetric total synthesis of (S)-(+)-cocaine and the first synthesis of cocaine C-1 analogs from N -sulfinyl β-amino ester ketals

Davis, Franklin A.,Theddu, Naresh,Edupuganti, Ram

supporting information; experimental part, p. 4118 - 4121 (2010/11/17)

Sulfinimine-derived α,β-unsaturated pyrrolidine nitrones, on heating with Al(O-t-Bu)3, undergo a highly stereoselective intramolecular [3 + 2] cycloaddition to give tricyclic isoxazolidines, which are transformed in three-steps to give C-1 substituted cocaine analogs.
