It is an ester formed from the reaction of methanesulfonic acid and (2R)-5-oxopyrrolidin-2-yl>methyl alcohol. <(2R)-5-oxopyrrolidin-2-yl>methyl methanesulfonate is often used as a protecting group for amines in organic chemistry reactions. It is also used in the production of various pharmaceuticals and agrochemicals. This chemical is a white crystalline solid with a faint odor and is considered to be stable under normal conditions. However, it should be handled with care as it can irritate the skin, eyes, and respiratory system upon contact or inhalation.Check Digit Verification of cas no
The CAS Registry Mumber 128811-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,1 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 128811-47:
(8*1)+(7*2)+(6*8)+(5*8)+(4*1)+(3*1)+(2*4)+(1*7)=132
132 % 10 = 2
So 128811-47-2 is a valid CAS Registry Number.
