1283090-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283090-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,0,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1283090-45:
(9*1)+(8*2)+(7*8)+(6*3)+(5*0)+(4*9)+(3*0)+(2*4)+(1*5)=148
148 % 10 = 8
So 1283090-45-8 is a valid CAS Registry Number.

Comparative study of the different approaches to the synthesis of isatins with a chiral substituent at the nitrogen atom
Kurkin,Bernovskaya,Yurovskaya
, p. 1208 - 1214 (2011)
Through a comparative study of three different routes to the synthesis of isatins with a chiral substituent on the nitrogen atom it has been shown that better results for preparing the isatins are achieved using the Sandmeyer (>99% ee, yield 50%) rather t
