Check Digit Verification of cas no

The CAS Registry Mumber 211228-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,2,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 211228-57:
(8*2)+(7*1)+(6*1)+(5*2)+(4*2)+(3*8)+(2*5)+(1*7)=88
88 % 10 = 8
So 211228-57-8 is a valid CAS Registry Number.

Facile preparation of aryl sulfides using palladium catalysis under mild conditions

Okauchi, Tatsuo,Kuramoto, Kouji,Kitamura, Mitsuru

supporting information; experimental part, p. 2891 - 2894 (2011/02/28)

A convenient method for C-S cross-coupling of aryl bromides with various thiols has been developed that involves the use of a 1,1′- bis(diphenylphosphino)ferrocene (DPPF)-ligated palladium complex with N,N-diisopropylethylamine (DIPEA) as the base. This coupling is tolerant of a wide range of functional groups, including hydroxy, amino, cyano, nitro, formyl, and carboxyl groups. Georg Thieme Verlag Stuttgart - New York.
