((2R,3R)-2-Methyl-3-vinyl-cyclopropyl)-urea is a chiral organic compound characterized by its unique cyclopropane ring structure, featuring a methyl group at the 2-position and a vinyl group at the 3-position. ((2R,3R)-2-Methyl-3-vinyl-cyclopropyl)-urea is a derivative of urea, with the cyclopropyl group attached to the nitrogen atoms of the urea moiety. The specific (2R,3R) configuration indicates that the molecule has two chiral centers with R (rectus) configuration, which means that the substituents at these centers follow the clockwise arrangement when viewed from the perspective of the priority of the substituents. ((2R,3R)-2-Methyl-3-vinyl-cyclopropyl)-urea may have potential applications in the fields of pharmaceuticals, agrochemicals, or as a chiral building block in organic synthesis, due to its unique stereochemistry and reactivity.
The CAS Registry Mumber 99779-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,7 and 9 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 99779-54: (7*9)+(6*9)+(5*7)+(4*7)+(3*9)+(2*5)+(1*4)=221 221 % 10 = 1 So 99779-54-1 is a valid CAS Registry Number.
