Check Digit Verification of cas no

The CAS Registry Mumber 20808-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20808-85:
(7*2)+(6*0)+(5*8)+(4*0)+(3*8)+(2*8)+(1*5)=99
99 % 10 = 9
So 20808-85-9 is a valid CAS Registry Number.

A Novel Addition-Rearrangement of O-(1-Benzotriazolylaklyl)oximes with Organolithium Reagents. Convenient Non-oxidative Conversions of Aldehydes into Amides

Katritzky, Alan R.,Jiang, Jinlong,Greenhill, John V.,Steel, Peter J.

, p. 3055 - 3060 (2007/10/02)

Condensation of an aldehyde, an oxime and benzotriazole gives an O-(1-benzotriazolylalkyl)oxime which undergoes an addition-rearrangement on treatment with an organolithium reagent.This reaction provides a novel non-oxidative method for the transformation of aldehydes into amides which has afforded several new N-monosubstituted amides with crowded structures.Grignard reactions of the O-(1-benzotriazolylalkyl)oximes give alcohols as the major products.
