Check Digit Verification of cas no

The CAS Registry Mumber 197149-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197149-92:
(8*1)+(7*9)+(6*7)+(5*1)+(4*4)+(3*9)+(2*9)+(1*2)=181
181 % 10 = 1
So 197149-92-1 is a valid CAS Registry Number.

Dialkyl phosphonates and tetraalkyl bis(phosphonate)s from the decomposition of quasi-phosphonium ylidic phosphonates in aqueous conditions

Griffiths, D. Vaughan,Karim, Khalku,Harris, Jayne E.

, p. 2539 - 2544 (2007/10/03)

The reaction of dimethyl benzoylphosphonates 1 (X = 2-halogen or 2-CF3O) with trialkyl phosphite leads to the formation of carbene intermediates 3 which are trapped by trialkyl phosphite to give the corresponding ylidic phosphonates 4. In acidi
