Check Digit Verification of cas no
The CAS Registry Mumber 87437-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,3 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87437-27:
(7*8)+(6*7)+(5*4)+(4*3)+(3*7)+(2*2)+(1*7)=162
162 % 10 = 2
So 87437-27-2 is a valid CAS Registry Number.

THE ORTHO-LITHIATION OF N,N,N',N'-TETRAMETHYLPHENYLPHOSPHONIC DIAMIDE
Dashan, Liu,Trippett, Stuart
, p. 2039 - 2040 (2007/10/02)
N,N,N',N'-Tetramethylphenylphosphonic diamide has been ortho-lithiated and the resulting aryl-lithium reacted with a series of electrophiles.Benzonitrile (2 moles) gave 8-bis(dimethylamino)phosphinyl-2,3a-diphenyl-1,3a-dihydrocycloheptimidazole (12).
