Check Digit Verification of cas no

The CAS Registry Mumber 1192216-82-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,2,1 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1192216-82:
(9*1)+(8*1)+(7*9)+(6*2)+(5*2)+(4*1)+(3*6)+(2*8)+(1*2)=142
142 % 10 = 2
So 1192216-82-2 is a valid CAS Registry Number.

Stereocontrolled generation of the (2R) chroman core of vitamin E: Total synthesis of (2R,4'RS,8'RS)-α-tocopherol

Hernandez-Torres, Gloria,Urbano, Antonio,Carmen Carreno,Colobert, Francoise

supporting information; experimental part, p. 4930 - 4933 (2010/01/16)

(2R,4'RS,8'RS)-α-Tocopherol (1) was prepared using, as the two key steps, a novel diastereoselective TiCl4-promoted (S)-sulfoxide-directed allylation of ketal 2 with allyl trimethyl silane 3 to efficiently generate the challenging (2R) stereocenter of the
