Check Digit Verification of cas no
The CAS Registry Mumber 75018-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,1 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75018-22:
(7*7)+(6*5)+(5*0)+(4*1)+(3*8)+(2*2)+(1*2)=113
113 % 10 = 3
So 75018-22-3 is a valid CAS Registry Number.

Dihydrothiazolopurines
Montgomery, John A.,Thomas, Jeanette H.
, p. 583 - 584 (2007/10/02)
Reaction of 1,2-dibromoethane with 2-mercaptoadenine gave both 4-amino-7,8-dihydrothiazolopurine (2) and the isomeric 3,6,7,9-tetrahydro-9-iminothiazolopurine (3).These tricyclic structures were identified by Raney nickel reduction to the corresponding 3- and 1-ethyladenines.
