Check Digit Verification of cas no

The CAS Registry Mumber 90543-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,4 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90543-18:
(7*9)+(6*0)+(5*5)+(4*4)+(3*3)+(2*1)+(1*8)=123
123 % 10 = 3
So 90543-18-3 is a valid CAS Registry Number.

, p. 585 - 621 (2007/10/02)

With acetylenic esters the (5-azolylimino)triphenylphosphoranes 10a-d do not show any cycloaddition tendency, while the (2-thienylimino)triphenylphosphoranes 8a,b yield the stable ylids 13a,b.By treatment with phenyl isocyanate the iminophosphoranes 16a-m
