1335207-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335207-53-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,0 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1335207-53:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*0)+(3*7)+(2*5)+(1*3)=128
128 % 10 = 8
So 1335207-53-8 is a valid CAS Registry Number.

Thiourea-catalyzed enantioselective iso-pictet-spengler reactions
Lee, Yunmi,Klausen, Rebekka S.,Jacobsen, Eric N.
, p. 5564 - 5567 (2011/12/03)
A one-pot condensation of isotryptamines and aldehydes that affords enantiomerically enriched 4-substituted tetrahydro-γ-carbolines is reported. The reaction is induced by a chiral thiourea/benzoic acid dual catalyst system. Purification of the N-Boc-prot
