Check Digit Verification of cas no
The CAS Registry Mumber 21230-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21230-41:
(7*2)+(6*1)+(5*2)+(4*3)+(3*0)+(2*4)+(1*1)=51
51 % 10 = 1
So 21230-41-1 is a valid CAS Registry Number.

Symmetrically and unsymmetrically bridged methylenebis(allopurinols): Synthesis of dimeric potential anti-gout drugs
Rosemeyer, Helmut,Anders, Martina,Seela, Frank
, p. 563 - 575 (2007)
Liquid-liquid phase transfer alkylation of 4-methoxy-pyrazolo[3,4-d]- pyrimidine (1a) with a dichloromethane/dibromomethane mixture (3:1, v/v) gave the regioisomeric methylenebis(heterocycles) 3a-5a. These were converted by dilute aqueous sodium hydroxide containing dimethylsulfoxide (DMSO) at concentrations between 0 and 60 vol-% into the methylenebis(allopurinols) 3b-5b by nucleophilic SNAr reactions at C(4). The effect of DMSO on the reaction kinetics was investigated.
