Check Digit Verification of cas no

The CAS Registry Mumber 1250259-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,2,5 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1250259-40:
(9*1)+(8*2)+(7*5)+(6*0)+(5*2)+(4*5)+(3*9)+(2*4)+(1*0)=125
125 % 10 = 5
So 1250259-40-5 is a valid CAS Registry Number.

Amide activation by Tf2O: Reduction of amides to amines by NaBH4 under mild conditions

Xiang, Shao-Hua,Xu, Jian,Yuan, Hong-Qiu,Huang, Pei-Qiang

supporting information; experimental part, p. 1829 - 1832 (2010/10/02)

An expeditious and practical method for the reduction of amides to amines is reported. The method is consisted of activation of amides with Tf 2O followed by reduction with sodium borohydride in THF at room temperature. Various amides/lactams gave the corresponding amines in good to excellent yields, even with hindered amides and secondary amides. This method also presents other advantages such as TBDPS-group tolerance, short reaction time, simple workup and purification procedure. Georg Thieme Verlag Stuttgart.
