856684-31-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 856684-31-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,6,8 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 856684-31:
(8*8)+(7*5)+(6*6)+(5*6)+(4*8)+(3*4)+(2*3)+(1*1)=216
216 % 10 = 6
So 856684-31-6 is a valid CAS Registry Number.

Synthesis of 4-substituted tetrahydropyridines by cross-coupling of enol phosphates
Larsen, Uffe S.,Martiny, Lars,Begtrup, Mikael
, p. 4261 - 4263 (2005)
Enol phosphates, synthesized from 4-piperidone, react by palladium catalyzed cross-coupling with arylboronic acids and by iron and palladium catalyzed cross-coupling with Grignard reagents to give 4-substituted tetrahydropyridines.
