130119-06-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130119-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,1 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130119-06:
(8*1)+(7*3)+(6*0)+(5*1)+(4*1)+(3*9)+(2*0)+(1*6)=71
71 % 10 = 1
So 130119-06-1 is a valid CAS Registry Number.

, p. 2121 - 2123 (2007/10/02)
3,4-Dibenzoyl-1-phenyl-2a,5-diazabenzazulene (2b) was synthesized by cycloaddition of 8-amino-3-phenyl-1-azaazulene with dibenzoylacetylene.Heteroannulation to 2b has been achieved by reactions with hydrazine and phosphorus pentasulfide.
