Check Digit Verification of cas no

The CAS Registry Mumber 342417-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,4,1 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 342417-89:
(8*3)+(7*4)+(6*2)+(5*4)+(4*1)+(3*7)+(2*8)+(1*9)=134
134 % 10 = 4
So 342417-89-4 is a valid CAS Registry Number.

Engstrom, Kenneth M.,Mendoza, Mario R.,Navarro-Villalobos, Mauricio,Gin, David Y.

, p. 1128 - 1130 (2001)

The direct stereoselective I111-mediated ocidative ring contraction of a protected 6-deoxy-D-gulal substrate to form a highly functinalized tetrahydrofurfural intermediate is a key step in the first total synthesis of (+)-pyrenlide D (see scheme; R = TBS = tert-butyldimethylsilyl).
