Check Digit Verification of cas no

The CAS Registry Mumber 1228657-94-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,5 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1228657-94:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*5)+(3*7)+(2*9)+(1*4)=180
180 % 10 = 0
So 1228657-94-0 is a valid CAS Registry Number.

A practical in situ generation of the schwartz reagent. reduction of tertiary amides to aldehydes and hydrozirconation

Zhao, Yigang,Snieckus, Victor

supporting information, p. 390 - 393 (2014/04/03)

A new, highly efficient in situ protocol (Cp2ZrCl2/LiAlH(OBu-t)3) is described for the generation of the Schwartz reagent which provides a convenient method for the amide to aldehyde reduction and the regioselective hydrozirconation-iodination of alkynes and alkenes. Highlighted are chemoselective reductions of benzamides derived by directed ortho metalation (DoM) chemistry, allowing the synthesis of valuable 1,2,3-substituted benzaldehydes. The single-step, three-component process proceeds in a very short reaction time, shows excellent functional group compatibility, and uses inexpensive and long-storage stable reducing reagents.
