Check Digit Verification of cas no
The CAS Registry Mumber 98051-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,5 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98051-42:
(7*9)+(6*8)+(5*0)+(4*5)+(3*1)+(2*4)+(1*2)=144
144 % 10 = 4
So 98051-42-4 is a valid CAS Registry Number.

Synthesis of α-Carbalkoxy Enethiols: A Class of Tautomeric Thiopyruvate Derivatives. Application to Griseoviridin
Butera, John,Rini, Josephine,Helquist, Paul
, p. 3676 - 3678 (2007/10/02)
A general approach to previously inaccessible α-carbalkoxy enethiols 1 is described (e.g., 4 -> 5 -> 6 -> 7), and the use of such substances in synthesis is illustrated (11).
