1609152-90-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609152-90-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,1,5 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1609152-90:
(9*1)+(8*6)+(7*0)+(6*9)+(5*1)+(4*5)+(3*2)+(2*9)+(1*0)=160
160 % 10 = 0
So 1609152-90-0 is a valid CAS Registry Number.

, p. 583 - 585 (2013)
A series of new N-heterocyclic or phenoxy substituted roflumilast analogues have been designed and synthesised. N-heterocyclic or phenoxy substituted benzaldehydes were first prepared from 3-hydroxy-4-methoxybenzaldehbyde and 1-bromo-3-chloropropane by an
