Check Digit Verification of cas no

The CAS Registry Mumber 1233211-51-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,2,1 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233211-51:
(9*1)+(8*2)+(7*3)+(6*3)+(5*2)+(4*1)+(3*1)+(2*5)+(1*1)=92
92 % 10 = 2
So 1233211-51-2 is a valid CAS Registry Number.

Facile double-lithiation of a transient urea: Vicarious ortho -metalation of aniline derivatives

Houlden, Chris E.,Lloyd-Jones, Guy C.,Booker-Milburn, Kevin I.

, p. 3090 - 3092 (2010)

A convenient one-pot method for the conversion of phenylisocyanate into ortho-functionalized aniline derivatives has been developed. The reaction proceeds via the selective ortho-metalation of a transient labile urea, which can be considered as a synthetic equivalent of 2-lithio-phenylisocyanate, a highly improbable intermediate.
