Check Digit Verification of cas no

The CAS Registry Mumber 1619921-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,9,2 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1619921-50:
(9*1)+(8*6)+(7*1)+(6*9)+(5*9)+(4*2)+(3*1)+(2*5)+(1*0)=184
184 % 10 = 4
So 1619921-50-4 is a valid CAS Registry Number.

Stereoselective synthesis of triarylethylenes via copper-palladium catalyzed decarboxylative cross-coupling: Synthesis of (Z)-tamoxifen

Cahiez, Gérard,Moyeux, Alban,Poizat, Ma?l

supporting information, p. 8982 - 8984 (2014/08/05)

The first Cu/Pd-catalyzed decarboxylative cross-coupling of 3,3-diarylacrylic acids with aryl bromides is described. Triarylethylenes were obtained in high yields with excellent stereoselectivities. This methodology was successfully applied to the stereos
