Check Digit Verification of cas no

The CAS Registry Mumber 89998-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89998-72:
(7*8)+(6*9)+(5*9)+(4*9)+(3*8)+(2*7)+(1*2)=231
231 % 10 = 1
So 89998-72-1 is a valid CAS Registry Number.

Acyclic Stereocontrol through Diastereo- and Enantioselective Sigmatropic Wittig Rearrangements

Tsai, David Jieh-Shyh,Midland, M.Mark

, p. 1842 - 1843 (1984)

High diastereoselection and complete transfer of chirality is observed in the Wittig rearrangements of optically active allyl (Z)-2-methylhex-4-en-3-yl ether.The acyclic stereoselection in the Wittig rearrangement of other (E)- and (Z)-allylic ethers is also examined.
