31906-04-4 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 31906-04-4 differently. You can refer to the following data:
1. Colorless liquid
2. Lyral is a colorless,
viscous liquid with a sweet odor reminiscent of lily of the valley. The aldehyde can
be prepared by a Diels–Alder reaction of myrcenol and acrolein in the presence
of a Lewis catalyst (e.g., zinc chloride).
Reaction ofmyrcenol with acrolein at elevated temperatures, without a catalyst,
yields a 70 : 30 mixture of the 4- and 3-substituted cyclohexene carboxaldehydes
.This mixture is a commercial product. The title compound has excellent
fixative properties and is used especially in soap and cosmetics perfumery：

Check Digit Verification of cas no
The CAS Registry Mumber 31906-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,0 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31906-04:
(7*3)+(6*1)+(5*9)+(4*0)+(3*6)+(2*0)+(1*4)=94
94 % 10 = 4
So 31906-04-4 is a valid CAS Registry Number.
