Check Digit Verification of cas no

The CAS Registry Mumber 856118-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,1,1 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 856118-83:
(8*8)+(7*5)+(6*6)+(5*1)+(4*1)+(3*8)+(2*8)+(1*3)=187
187 % 10 = 7
So 856118-83-7 is a valid CAS Registry Number.

Tandem one-pot synthesis of polysubstituted NH-pyrroles involving the palladium-catalyzed intramolecular oxidative amination of the zinc bromide complex of β-enamino esters

Kim, Ju Hyun,Choi, Suh Young,Bouffard, Jean,Lee, Sang-Gi

, p. 9253 - 9261 (2014)

The Pd-catalyzed oxidative olefin amination of the zinc bromide complex intermediate, formed by the sequential reaction of nitriles with a Reformatsky reagent and 1-alkynes, affords pyrrole derivatives in good to excellent yields. This tandem protocol pro
