Check Digit Verification of cas no

The CAS Registry Mumber 117911-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,1 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117911-76:
(8*1)+(7*1)+(6*7)+(5*9)+(4*1)+(3*1)+(2*7)+(1*6)=129
129 % 10 = 9
So 117911-76-9 is a valid CAS Registry Number.

S(N)2 at nitrogen: The reaction of N-(4-cyanophenyl)-O-diphenylphosphinoylhydroxylamine with N-methylaniline. A model for the reactions of ultimate carcinogens of aromatic amines with (bio)nucleophiles

Ulbrich,Famulok,Bosold,Boche

, p. 1689 - 1692 (2007/10/02)

The model reaction of 5 with 6 to give 7 and 8 (≥90%) follows the S(N)2 mechanism. From this result and from product studies it is concluded that the reactions of the ultimate carcinogen 1 with 6 and deoxyguanosine (dG) (and hence of other ultimate carcinogens of aromatic amines with bionucleophiles) follow the same mechanism.
