636-65-7 Usage
Preparation
N-CBZ-γ-benzyl-L-isoglutamine (5 gm.) was dissolved in 100 ml. of 50% ethanol and hydrogenated for 12 hr. at room temperature and atmospheric pressure in the presence of palladium catalyst (5% Pd on calcium carbonate). The catalyst was filtered off and a trace of calcium ions was removed with oxalic acid. The solution was evaporated to dryness, the residue dissolved in a small amount of hot water, and the solution treated with charcoal. Alcohol was added to the cloud point and L-isoglutamine was recovered from the chilled solution as fine white crystals, m.p. 186-188°, yield 65%.
Chemical Properties
White to off-white powder
Check Digit Verification of cas no
The CAS Registry Mumber 636-65-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 636-65:
(5*6)+(4*3)+(3*6)+(2*6)+(1*5)=77
77 % 10 = 7
So 636-65-7 is a valid CAS Registry Number.
