Check Digit Verification of cas no

The CAS Registry Mumber 1609086-27-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,0,8 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1609086-27:
(9*1)+(8*6)+(7*0)+(6*9)+(5*0)+(4*8)+(3*6)+(2*2)+(1*7)=172
172 % 10 = 2
So 1609086-27-2 is a valid CAS Registry Number.

Tungsten-catalyzed regioselective and stereospecific ring opening of 2,3-epoxy alcohols and 2,3-epoxy sulfonamides

Wang, Chuan,Yamamoto, Hisashi

supporting information, p. 6888 - 6891 (2014/06/09)

The first catalytic, highly C3-selective, stereosepecific ring-opening reaction of 2,3-epoxy alcohols and 2,3-epoxy sulfonamides has been accomplished. This process was efficiently promoted by W-salts, and the developed method was applicable to various epoxides with diverse N-and O-nucleophiles affording the products in good to excellent yields (up to 95%) and generally with high regioselectivities (C3:C2 up to >99:1).
