1233532-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233532-12-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,5,3 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1233532-12:
(9*1)+(8*2)+(7*3)+(6*3)+(5*5)+(4*3)+(3*2)+(2*1)+(1*2)=111
111 % 10 = 1
So 1233532-12-1 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 (2010)
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
