201797-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 201797-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,9 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 201797-77:
(8*2)+(7*0)+(6*1)+(5*7)+(4*9)+(3*7)+(2*7)+(1*7)=135
135 % 10 = 5
So 201797-77-5 is a valid CAS Registry Number.

Racemates and enantiomers of basic substituted 5-phenylhydantoins. Syntheses and antiarrhythmic activity
Knabe,Baldauf,Ahlhelm
, p. 912 - 919 (2007/10/03)
The racemates and the enantiomers of 5-phenylhydantoins with basic substituents in 5-position are synthesized on two different routes via the Bucherer-Bergs-reaction. Using lanthanide-shift-reagents the enantiomeric excess for the enantiomers of 3-methyl-
