Check Digit Verification of cas no

The CAS Registry Mumber 856131-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,1,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 856131-99:
(8*8)+(7*5)+(6*6)+(5*1)+(4*3)+(3*1)+(2*9)+(1*9)=182
182 % 10 = 2
So 856131-99-2 is a valid CAS Registry Number.

Ag-Catalyzed Intramolecular Sequential Vicinal Diamination of Alkynes with Isocyanates: Synthesis of Fused Indole-Cyclic Urea Derivatives

Rajesh, Manda,Puri, Surendra,Kant, Ruchir,Sridhar Reddy, Maddi

, p. 5169 - 5177 (2017)

A formal intramolecular vicinal 1,2-diamination of alkynes is achieved for the synthesis of indole-cyclic urea fused derivatives through a double cyclization process from readily available aminophenyl propargyl alcohols. This sequential triple C-N bond co
