Check Digit Verification of cas no

The CAS Registry Mumber 1357181-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,1,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1357181-52:
(9*1)+(8*3)+(7*5)+(6*7)+(5*1)+(4*8)+(3*1)+(2*5)+(1*2)=162
162 % 10 = 2
So 1357181-52-2 is a valid CAS Registry Number.

New type of azacyclization: Thermal preparation of 4,6-disubstituted 2-piperidinone from N-sulfonyldienamide and its substituent effect

Maekawa, Yuya,Sakaguchi, Taku,Tsuchikawa, Hiroshi,Katsumura, Shigeo

, p. 837 - 841 (2012/03/09)

The thermal 6-endo cyclization of N-sulfonyl-2,4-dienamide compounds to produce 4,6-disubstituted 2-piperidinone is described. The observed remarkable substituent effect due to the N-sulfonyl and C3 ethoxycarbonyl groups for acceleration of this 6-endo cy
