1609564-20-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609564-20-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,5,6 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1609564-20:
(9*1)+(8*6)+(7*0)+(6*9)+(5*5)+(4*6)+(3*4)+(2*2)+(1*0)=176
176 % 10 = 6
So 1609564-20-6 is a valid CAS Registry Number.

Stereoselective total synthesis of almorexant
Reddy, N. Siva Senkar,Reddy, B.V. Subba
, p. 3157 - 3159 (2014/05/20)
A highly stereoselective synthesis of almorexant has been achieved using (R)-tert-butanesulfinamide as a chiral source. The chiral tetrahydroisoquinoline core was constructed through allylation of chiral N-sulfinyl imine followed by ring closure of the se
