Check Digit Verification of cas no
The CAS Registry Mumber 100419-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,1 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100419-00:
(8*1)+(7*0)+(6*0)+(5*4)+(4*1)+(3*9)+(2*0)+(1*0)=59
59 % 10 = 9
So 100419-00-9 is a valid CAS Registry Number.

1,3-Dithienium- and 1,3-Dithiolenium Salts, III. Synthesis of Cyclic Dithioacetals of β-Keto Esters from Ketene Silyl Acetals
Stahl, Ingfried
, p. 3159 - 3165 (2007/10/02)
The 1,3-dithian-2-ylium tetrafluoroborates 3, available by different methods, react in good yields with the ketene silyl acetals 2 to give the new cyclic dithioacetals 4 which are deacetalized to the β-keto esters 5 and 9.
