Urea, (trimethylsilyl)-, also known as trimethylsilyl urea or TMS urea, is an organosilicon compound with the chemical formula (CH3)3Si-NH2CONH2. It is a white crystalline solid that is soluble in organic solvents and is commonly used as a silylating agent in organic synthesis and as a protecting group in peptide synthesis. TMS urea is formed by the reaction of urea with trimethylsilyl chloride (TMSCl) in the presence of a base, such as triethylamine. The compound is known for its ability to form stable silyl ethers with alcohols and amines, which can be useful in various chemical reactions and analyses.

Check Digit Verification of cas no

The CAS Registry Mumber 18148-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18148-61:
(7*1)+(6*8)+(5*1)+(4*4)+(3*8)+(2*6)+(1*1)=113
113 % 10 = 3
So 18148-61-3 is a valid CAS Registry Number.
