Check Digit Verification of cas no

The CAS Registry Mumber 198693-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198693-91:
(8*1)+(7*9)+(6*8)+(5*6)+(4*9)+(3*3)+(2*9)+(1*1)=213
213 % 10 = 3
So 198693-91-3 is a valid CAS Registry Number.

Siamyl Glyoxylate as an Efficient Enophile in the Lewis Acid Mediated Glyoxylate Ene-Reaction with Allylic Ethers. Application to the Synthesis of a Taxol A-Ring Subunit

Wennerberg, Johan,Polla, Magnus,Frejd, Torbjoern

, p. 8735 - 8740 (1997)

In contrast to other simple alkyl glyoxylates, siamyl glyoxylate (1a) proved to be an effective enophile in the glyoxylate ene-reaction with the allylic ether 2a, which we earlier used for the synthesis of the A-ring subunit of taxol.
