1187670-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187670-97-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,6,7 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1187670-97:
(9*1)+(8*1)+(7*8)+(6*7)+(5*6)+(4*7)+(3*0)+(2*9)+(1*7)=198
198 % 10 = 8
So 1187670-97-8 is a valid CAS Registry Number.

Synthesis of isatins with a chiral substituent at the nitrogen atom
Kurkin, Alexander V.,Bernovskaya, Anna A.,Yurovskaya, Marina A.
experimental part, p. 1500 - 1505 (2009/12/01)
(R)-Ethyl 2-(isatin-1-yl)propanoates 8a-c were prepared from the corresponding (R)-arylalanines by Sandmeyer's method in high yield and good enantioselectivity (up to 99%). The key step of the process is the Mitsunobu reaction.
