Check Digit Verification of cas no

The CAS Registry Mumber 38940-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38940-28:
(7*3)+(6*8)+(5*9)+(4*4)+(3*0)+(2*2)+(1*8)=142
142 % 10 = 2
So 38940-28-2 is a valid CAS Registry Number.

Synthesis of β-aminoketones and construction of highly substituted 4-piperidones by mannich reaction induced by persistent radical cation salts

Jia, Xiao-Dong,Wang, Xiao-E.,Yang, Cai-Xia,Huo, Cong-De,Wang, Wen-Juan,Ren, Yan,Wang, Xi-Cun

supporting information; experimental part, p. 732 - 735 (2010/04/02)

A Mannich reaction of imines and ketones induced by persistent radical cation salts was Investigated, and a series of Mannich bases, β-amlnoketones, were synthesized. A novel cyclization to form the 4-piperidone skeleton was achieved In a tandem process. The reaction can be rationalized as a radical cation process supported by various evidence.
