Check Digit Verification of cas no

The CAS Registry Mumber 870672-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,6,7 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 870672-30:
(8*8)+(7*7)+(6*0)+(5*6)+(4*7)+(3*2)+(2*3)+(1*0)=183
183 % 10 = 3
So 870672-30-3 is a valid CAS Registry Number.

Exploiting the dual reactivity of o-isocyanobenzamide: Three-component synthesis of 4-imino-4H-3,1-benzoxazines

Bonne, Damien,Dekhane, Mouloud,Zhu, Jieping

, p. 5285 - 5288 (2007/10/03)

(Chemical Equation Presented) A multicomponent synthesis of 4-imino-4H-3,1-benzoxazines is developed. Heating a toluene solution of an aldehyde (6), an amine (7), and an isonitrile (5) in the presence of a stoichiometric amount of ammonium chloride at 60°C for 12 h produces the title compound in good to excellent yields.
