1351433-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1351433-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,1,4,3 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1351433-25:
(9*1)+(8*3)+(7*5)+(6*1)+(5*4)+(4*3)+(3*3)+(2*2)+(1*5)=124
124 % 10 = 4
So 1351433-25-4 is a valid CAS Registry Number.

, p. 1016 - 1018 (2012/02/05)
Reactions of malonothioamides with acetylenedicarboxylates proceed as an addition of the sulfur atom at the triple bond with subsequent intramolecular reaction between the ester group and the nitrogen atom, that leads to substituted thiazolidines. Unsubst
