1268603-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268603-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,6,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1268603-21:
(9*1)+(8*2)+(7*6)+(6*8)+(5*6)+(4*0)+(3*3)+(2*2)+(1*1)=159
159 % 10 = 9
So 1268603-21-9 is a valid CAS Registry Number.

Indoline-3-carboxylic acid derived organocatalysts for the anti-mannich reaction
Pietruszka, Joerg,Simon, Robert Christian
, p. 14534 - 14544 (2011/03/20)
Mannich type reactions of a preformed aldimine with various carbonyl compounds were investigated with a series of functionalised indoline derivatives as catalysts: indoline-3-carboxylic acid, the diphenylcarbinol analogue and O-protected silyl ether analo
