Check Digit Verification of cas no

The CAS Registry Mumber 1217897-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217897-43:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*9)+(3*7)+(2*4)+(1*3)=182
182 % 10 = 2
So 1217897-43-2 is a valid CAS Registry Number.

Synthetic application of in situ generation of N-acyliminium ions from α-amido p-tolylsulfones for the synthesis of α-amino nitriles

Kadam, Santosh T.,Thirupathi, Ponnaboina,Kim, Sung Soo

experimental part, p. 1684 - 1688 (2010/04/04)

In the presence of catalytic amount of bismuth bromide (5 mol %) the α-amido p-tolylsulfones are converted into N-acyliminium ions, which undergo the nucleophilic addition of trimethylsilyl cyanide (TMSCN) to provide the N-protected α-amino nitriles in very good yield. A variety of α-amido p-tolylsulfones were prepared from aromatic as well as aliphatic aldehydes for the synthesis of α-amino nitriles.
