Check Digit Verification of cas no

The CAS Registry Mumber 90997-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90997-21:
(7*9)+(6*0)+(5*9)+(4*9)+(3*7)+(2*2)+(1*1)=170
170 % 10 = 0
So 90997-21-0 is a valid CAS Registry Number.

Synthesis and Spontaneous Racemization of Benzanthracene 1,2-Oxide

Boyd, Derek R.,Sharma, Narain D.

, p. 839 - 841 (2007/10/02)

Benzanthracene 1,2-oxide (1,2-epoxy-1,2-dihydrobenzanthracene), a minor metabolite of benzanthracene in hepatic systems, has been synthesized both from racemic precursors and from separated diastereoisomeric bromohydrin esters whose absolute ster

AN IMPROVED METHOD FOR THE SYNTHESIS OF OPTICALLY PURE EPOXIDE AND ALCOHOL DERIVATIVES OF CHIRAL BROMOHYDRINS

Balani, Suresh K.,Boyd, Derek R.,Cassidy, E. Sally,Greene, Ruth M. E.,McCombe, Kenneth M.,et. al.

, p. 3277 - 3280 (2007/10/02)

The resolution of arene oxides, diols and other derivatives of bromohydrins has been markedly improved by the use of bromohydrin esters of (-)-(S)-α-methoxy-α-trifluoromethyl-phenylacetic acid (MTPA).
