Check Digit Verification of cas no

The CAS Registry Mumber 1221071-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1221071-87:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*7)+(3*1)+(2*8)+(1*7)=99
99 % 10 = 9
So 1221071-87-9 is a valid CAS Registry Number.

Mimics of a R22(8) hydrogen-bond dimer motif: Synthesis and influence on the crystallisation of sulfathiazole and sulfapyridine

Lawrence, Simon E.,McAuliffe, Marie T.,Moynihan, Humphrey A.

experimental part, p. 1134 - 1141 (2010/04/29)

The bis[4-(hydroxyamino)phenylsulfonyl]piperazine 5, diketopiperazine 10 and benzene 14 were synthesised as mimics of an R22(8) motif, which occurs in one crystal polymorph of sulfathlazole and in several polymorphs of sulfapyridine.
