Check Digit Verification of cas no
The CAS Registry Mumber 671222-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,1,2,2 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 671222-97:
(8*6)+(7*7)+(6*1)+(5*2)+(4*2)+(3*2)+(2*9)+(1*7)=152
152 % 10 = 2
So 671222-97-2 is a valid CAS Registry Number.

Synthesis of the first fluoro(phosphanyl)- and diphosphanyl-stannanes and surprising formation of [P(SnMe3)4]+SiF 5- ?
Driess, Matthias,Merz, Klaus,Monse, Christian
, p. 2608 - 2609 (2007/10/03)
Monophosphanylation of the difluorostannane Is2SnF2 (Is = 2,4,6-triisopropylphenyl) with Si(PH2)4 furnishes the first isolable fluoro(phosphanyl)stannane IS2Sn(F)PH2 1, which readily underg
