Check Digit Verification of cas no

The CAS Registry Mumber 188200-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,2,0 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188200-31:
(8*1)+(7*8)+(6*8)+(5*2)+(4*0)+(3*0)+(2*3)+(1*1)=129
129 % 10 = 9
So 188200-31-9 is a valid CAS Registry Number.

Synthetic studies towards furosesquiterpenes: Construction of linearly-fused A/B trans- and A/B cis-furo[3,2-b]-and furo[3,2-b]- and furo[2,3-b] decalins

Chakraborty, Arindam,Kar, Gandhi K.,Ray, Jayanta K.

, p. 2989 - 2996 (1997)

Linearly fused furo[2,3-b] and furo[3,2-b]decalin systems with cis/trans ring junctions are present in several furosesquiterpenes obtained from marine sponges. A short and efficient synthesis of this ring system is described starting from Hageman's ester (1). The method has been extended for the synthesis of compound 8 and 14 via the diketones 5,6 and 12 respectively.
