Check Digit Verification of cas no

The CAS Registry Mumber 470475-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,0,4,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 470475-57:
(8*4)+(7*7)+(6*0)+(5*4)+(4*7)+(3*5)+(2*5)+(1*7)=161
161 % 10 = 1
So 470475-57-1 is a valid CAS Registry Number.

Orita, Akihiro,De, Lie An,Nakano, Takehiko,Yaruva, Jayamma,Ma, Nianchun,Otera, Junzo

, p. 2005 - 2010 (2007/10/03)

A new strategy for constructing enantiopure acetylenic cyclophanes is described on the basis of one-pot double elimination reaction starting from dialdehydes and bis(sulfoximine)s. In this case, the conventional sulfone protocol affords poorer yields of t
