135735-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135735-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,3 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135735-29:
(8*1)+(7*3)+(6*5)+(5*7)+(4*3)+(3*5)+(2*2)+(1*9)=134
134 % 10 = 4
So 135735-29-4 is a valid CAS Registry Number.

(E)-α-Phenylcinnamic acids (2) on heating with pyridine/POCl3 have been found to afford the corresponding 3-phenylcoumarins (5).However, with diazomethane the acids 2 give the corresponding (E)-esters (4) and not the isomeric (Z)-acids (3).
