1620286-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620286-16-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,2,8 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1620286-16:
(9*1)+(8*6)+(7*2)+(6*0)+(5*2)+(4*8)+(3*6)+(2*1)+(1*6)=139
139 % 10 = 9
So 1620286-16-9 is a valid CAS Registry Number.

Interaction of 2-naphthol with γ-ureidoacetals. A new method for the synthesis of 2-arylpyrrolidines
Gazizov,Smolobochkin,Burilov,Pudovik
, p. 707 - 714 (2014)
We report a new, single-stage method for the synthesis of 2-arylpyrrolidines, based on an acid-catalyzed reaction of 2-naphthol with γ-ureidoacetals, enabling the preparation of the target compounds under mild conditions, while avoiding costly reagents an
