Check Digit Verification of cas no

The CAS Registry Mumber 778581-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,5,8 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 778581-74:
(8*7)+(7*7)+(6*8)+(5*5)+(4*8)+(3*1)+(2*7)+(1*4)=231
231 % 10 = 1
So 778581-74-1 is a valid CAS Registry Number.

experimental part, p. 493 - 497 (2010/04/26)

Chlorotrimethylsilane-promoted double Mannich annulation of ketones using N,N-bis(methoxymethyl)benzylamine has been explored. It has been shown that the structure of the substrate drastically influenced the outcome of the reaction. The method allows azabicyclo[n.3.1]alkane derivatives (n=2-5) to be obtained in good yields.
