892874-83-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 892874-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,8,7 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 892874-83:
(8*8)+(7*9)+(6*2)+(5*8)+(4*7)+(3*4)+(2*8)+(1*3)=238
238 % 10 = 8
So 892874-83-8 is a valid CAS Registry Number.

The reaction of anilines, benzaldehydes, and ethyl 3,3-diethoxypropionate in the presence of Yb(OTf)3 proceeded under mild reaction conditions to give dihydropyridines (DHPs). We have found that the reaction depended on the solvent and the DHPs
