157039-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157039-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,3 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157039-25:
(8*1)+(7*5)+(6*7)+(5*0)+(4*3)+(3*9)+(2*2)+(1*5)=133
133 % 10 = 3
So 157039-25-3 is a valid CAS Registry Number.

CNS-active pyrans: Amine- and aryl-substituted 6,8-dioxabicyclo-octanes
Eiden,Denk,Hofner
, p. 405 - 412 (2007/10/02)
The amin- and phenyl substituted 6,8-dioxabicyclooctanes 10 and 11 show distinct CNS-activities. Intensity and profile depend on the type of amine and the stereochemistry of the products. Therefore, we have synthesized 6,8-dioxabicyclooctanes with differe
