138058-67-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138058-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,5 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138058-67:
(8*1)+(7*3)+(6*8)+(5*0)+(4*5)+(3*8)+(2*6)+(1*7)=140
140 % 10 = 0
So 138058-67-0 is a valid CAS Registry Number.

, p. 7925 - 7036 (1991)
Norephedrine derived 2-methoxy-2-methyl oxazolidine 2 is an efficient stereoselective acetylating agent in reactions with stereogenic silylenolethers and silylketenethiolacetals. Moderate selectivity is also obtained upon acetylation of crotyltin reagents
