Check Digit Verification of cas no

The CAS Registry Mumber 190263-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,6 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 190263-13:
(8*1)+(7*9)+(6*0)+(5*2)+(4*6)+(3*3)+(2*1)+(1*3)=119
119 % 10 = 9
So 190263-13-9 is a valid CAS Registry Number.

Electrophilic cyanations. I. Synthesis of thiocyanato-heteroarenes and tosylheteroarenes from mercapto-heteroarenes using p-toluenesulfonyl cyanide

Miyashita, Akira,Nagasaki, Izuru,Kawano, Akiko,Suzuki, Yumiko,Iwamoto, Ken-Ichi,Higashino, Takeo

, p. 745 - 755 (2007/10/03)

Mercaptoheteroarenes (1) underwent electrophilic cyanation with p-toluenesulfonyl cyanide (TsCN) in THF in the presence of NaH to give the corresponding thiocyanatoheteroarenes (2) in moderate to good yields. In DMF, tosylheteroarenes (4) were formed by substitution with p-toluenesulfinate ion through thiocyanatoheteroarenes (2).
