Check Digit Verification of cas no

The CAS Registry Mumber 161123-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,2 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161123-34:
(8*1)+(7*6)+(6*1)+(5*1)+(4*2)+(3*3)+(2*3)+(1*4)=88
88 % 10 = 8
So 161123-34-8 is a valid CAS Registry Number.

Highly diastereoselective strecker reaction of enolizable aliphatic sulfinimines

Li, Bin-Feng,Yuan, Ke,Zhang, Ming-Jie,Wu, Hao,Dai, Li-Xin,Wang, Quan Rui,Hou, Xue-Long

, p. 6264 - 6267 (2007/10/03)

The reaction of chiral sulfinimines 1c-g derived from aliphatic aldehydes with TMSCN in the presence of CsF gave α-amino nitriles in high diastereoselectivity and yield. α,β-Diamino acid derivatives were also obtained in high diastereoselectivity from the reaction of 2-aziridinesulfinimines 1h and 1i followed by ring-opening of the products with thiophenol. The presence ofhydrogen of hydrogen at the α-position of the C=N double bond is crucial in this TMSCN addition reaction.
