Check Digit Verification of cas no
The CAS Registry Mumber 1206694-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,6,9 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1206694-32:
(9*1)+(8*2)+(7*0)+(6*6)+(5*6)+(4*9)+(3*4)+(2*3)+(1*2)=147
147 % 10 = 7
So 1206694-32-7 is a valid CAS Registry Number.

[Chemical equation presented] The chemoselectivity in the amination of 4-chloroquinazolines with 3-amino-1H-pyrazoles was studied. Under the conditions of Pd2(dba)3/ Xantphos/Na2CO3, 4-chloroquinazolines underwent selective amination with the cyclic secondary amino group of 3-amino-1H-pyrazoles. whereas 4-chloroquinazolines were exclusively aminated with the primary amino group of 3-amino-1H-pyrazoles via SNAr substitution In the presence of HCl.
