127-42-4 Usage
Description
Methyl-α-ionone has an odor similar to α-ionone but lighter and
more rounded with a pleasant, fruity, and sweet nuance. May be
prepared by condensation of citral with methyl ethyl ketone (see
methyl y-ionone or α-iso-methylionone).Pectic enzymes are indispensable for making high-density fruit juice concentrates or purees. Enzyme depectinization is required for apple juice concentrate of about 72° Brix, which is made on a large scale, as otherwise a gel would result rather than the desired liquid concentrate. Pectic enzymes are useful in treating orange, grape and prune pulps prior to vacuum puff drying.

Check Digit Verification of cas no
The CAS Registry Mumber 127-42-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127-42:
(5*1)+(4*2)+(3*7)+(2*4)+(1*2)=44
44 % 10 = 4
So 127-42-4 is a valid CAS Registry Number.
