123872-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123872-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,7 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123872-32:
(8*1)+(7*2)+(6*3)+(5*8)+(4*7)+(3*2)+(2*3)+(1*2)=122
122 % 10 = 2
So 123872-32-2 is a valid CAS Registry Number.

Condensation of 2,4-dimethyl-1,3-butadiene-1,4-sultone (1) with phenylenediamines gave the sultams 2a-e. The sultams 2 react with phenylisocyanate, p-anisylisocyanate or p-chlorophenylisocyanate to give the phenylurea derivatives 2d-l. Sultam 2c reacts wi
