1224597-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1224597-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,5,9 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1224597-75:
(9*1)+(8*2)+(7*2)+(6*4)+(5*5)+(4*9)+(3*7)+(2*7)+(1*5)=164
164 % 10 = 4
So 1224597-75-4 is a valid CAS Registry Number.

experimental part, p. 1333 - 1338 (2010/06/21)
Under microwave irradiation, vanillin was alkylated with α,W-dihaloalkane to give 4,4'-alkylene-bridging vanillins, which in turn underwent one-pot multicomponent reactions with excess of ethyl acetoacetate and ammonium bicarbonate to give 4,4'-alkoxy-bri
