Check Digit Verification of cas no

The CAS Registry Mumber 730971-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,0,9,7 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 730971-81:
(8*7)+(7*3)+(6*0)+(5*9)+(4*7)+(3*1)+(2*8)+(1*1)=170
170 % 10 = 0
So 730971-81-0 is a valid CAS Registry Number.

Synthesis and spectral studies (FT-IR, 1H, 13C, 119Sn, and mass spectrometry) of mixed organotin(IV) compounds containing a long chain alkyl group (n-C7H15)

Sadiq-ur-Rehman,Ali, Saqib,Badshah, Amin

, p. 443 - 457 (2004)

Di- and triorganotin(IV) compounds of the type R2SnR 2′ and R3SnR′ (R = CH3, n-C 4H9, C6H5, C6H 5CH2 and R′ = n-C7H15) have been prepared by the reaction of R2SnCl2 and R 3SnCl with a stoichiometric amount of n-heptylmagnesium bromide, prepared in situ in dry diethyl ether. The products obtained were vacuum distilled. The structural assignments were made on the basis of spectral studies such as FT-IR, 1H, 13C, 119Sn NMR, and mass spectrometry which ascertain the tetrahedral environment around the tin atom.
