Check Digit Verification of cas no
The CAS Registry Mumber 117872-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,7 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117872-75:
(8*1)+(7*1)+(6*7)+(5*8)+(4*7)+(3*2)+(2*7)+(1*5)=150
150 % 10 = 0
So 117872-75-0 is a valid CAS Registry Number.

2,2-Difluoro-1,3,2-oxazaborolidin-5-ones: Novel approach for selective side-chain protection of serine and threonine

, p. 621 - 624 (1997)
2,2-Difluoro-1,3,2-oxazaborolidin-5-ones 1, which are synthesized from BF3 and salts of amino acids, are highly effective, convenient and, moreover, inexpensive intermediates for the simultaneous protection of both α-amino and α-carboxy groups in α-amino acids. The new method streamlines the hitherto tedious procedures for side-chain protection of Ser and Thr. Ser(Bu′), Thr(Bu′), Ser(Bzl) and Thr(Bzl) are obtained by this procedure in high yields and in pure form using highly reactive reagents.
