Check Digit Verification of cas no

The CAS Registry Mumber 1607804-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,7,8,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1607804-90:
(9*1)+(8*6)+(7*0)+(6*7)+(5*8)+(4*0)+(3*4)+(2*9)+(1*0)=169
169 % 10 = 9
So 1607804-90-9 is a valid CAS Registry Number.

AgSCF3/Na2S2O8-Promoted Trifluoromethylthiolation/Cyclization of o-Propargyl Arylazides/ o-Alkynyl Benzylazides: Synthesis of SCF3-Substituted Quinolines and Isoquinolines

Qiu, Yi-Feng,Niu, Yue-Jie,Wei, Xi,Cao, Bao-Qian,Wang, Xi-Cun,Quan, Zheng-Jun

, p. 4165 - 4178 (2019)

A AgSCF3/Na2S2O8-promoted trifluoromethylthiolation/cascade cyclization of o-propargyl arylazides (or o-alkynyl benzylazides) triggered by a carbon-carbon triple bond is reported. This strategy provides the synthesis of valuable SCF3-substituted quinoline and isoquinoline systems via the construction of one C(sp2)-SCF3 bond and one C-N bond within one process.
