1581258-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1581258-84-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,2,5 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1581258-84:
(9*1)+(8*5)+(7*8)+(6*1)+(5*2)+(4*5)+(3*8)+(2*8)+(1*4)=185
185 % 10 = 5
So 1581258-84-5 is a valid CAS Registry Number.

Specific intramolecular aromatic C–H insertion of diazosulfonamides
Huang, Peipei,Yang, Zhanhui,Xu, Jiaxi
, p. 3255 - 3265 (2017/05/12)
The chemoselectivity in the intramolecular C–H insertion of various diazosulfonamides has been experimentally studied. The results reveal that the aliphatic 1,4-, 1,5-, or 1,6-C(sp3)?H insertions of diazosulfonamides are not accessible, while t
