Check Digit Verification of cas no

The CAS Registry Mumber 857350-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,3,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 857350-22:
(8*8)+(7*5)+(6*7)+(5*3)+(4*5)+(3*0)+(2*2)+(1*2)=182
182 % 10 = 2
So 857350-22-2 is a valid CAS Registry Number.

Sequential cross-coupling of 1,4-bissilylbutadienes: Synthesis of unsymmetrical 1,4-disubstituted 1,3-butadienes

Denmark, Scott E.,Tymonko, Steven A.

, p. 8004 - 8005 (2007/10/03)

A mild and general and stereospecific cross-coupling reaction of unsymmetrical 1,4-bissilyl-1,3-butadienes has been accomplished. By the use of either a benzyldimethylsilyl or 2-thienyldimethylsilyl unit at one end of the dienylsilanol, a selective cross-
