157891-22-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157891-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,8,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157891-22:
(8*1)+(7*5)+(6*7)+(5*8)+(4*9)+(3*1)+(2*2)+(1*2)=170
170 % 10 = 0
So 157891-22-0 is a valid CAS Registry Number.

A SHORT SYNTHESIS OF A CONFORMATIONALLY RESTRICTED ANALOG OF THE NEUROTRANSMITTER SEROTONIN WITH REDUCED BASICITY
Macor, John E.,Ryan, Kevin
, p. 1447 - 1450 (2007/10/02)
The synthesis of a less basic, conformationally restricted analog of serotonin is described .The crucial carbon-carbon bond formation step in this synthesis involves the attack of a 2-lithioimidazole anion on an
