398142-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 398142-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,8,1,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 398142-17:
(8*3)+(7*9)+(6*8)+(5*1)+(4*4)+(3*2)+(2*1)+(1*7)=171
171 % 10 = 1
So 398142-17-1 is a valid CAS Registry Number.

Asymmetric iodolactonization utilizing chiral squaramides
Tungen, Jorn E.,Nolsoe, Jens M. J.,Hansen, Trond V.
, p. 5884 - 5887 (2013/02/23)
Asymmetric iodolactonization of γ- and δ-unsaturated carboxylic acids has been explored in the presence of six different chiral organocatalysts 5-8. The catalyst 6b was found to facilitate the cyclization of 5-arylhex-5-enoic acids 1 to the corresponding
