29681-45-6 Usage

Chemical Properties

METHYL 5-METHYLNICOTINATE is White Crystalline Solid

Uses

Different sources of media describe the Uses of 29681-45-6 differently. You can refer to the following data:
1. METHYL 5-METHYLNICOTINATE is a metabolite of Nicotine. Used for the synthesis of (5-methylpyridin-3-yl)methanol, a key intermediate of Rupatadine fumarate.
2. 5-Methyl-N?-nitrosonornicotine (5-MeNNN) was synthesized from methyl 5-methylnicotinate. 5-Methyl-N?-nitrosonornicotine is used as the starting material in organic compound synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 29681-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,8 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 29681-45:
(7*2)+(6*9)+(5*6)+(4*8)+(3*1)+(2*4)+(1*5)=146
146 % 10 = 6
So 29681-45-6 is a valid CAS Registry Number.
