Check Digit Verification of cas no
The CAS Registry Mumber 1010690-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,0,6,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1010690-99:
(9*1)+(8*0)+(7*1)+(6*0)+(5*6)+(4*9)+(3*0)+(2*9)+(1*9)=109
109 % 10 = 9
So 1010690-99-9 is a valid CAS Registry Number.

Mild method for the synthesis of 1H-indazoles through oxime-phosphonium ion intermediate
Paul, Saurav,Panda, Subhankar,Manna, Debasis
supporting information, p. 2480 - 2483 (2014/05/06)
The synthesis of 1H-indazoles from o-aminobenzoximes is achieved via N-N bond formation using triphenylphosphine, I2, and imidazole. Selective formation of oxime-phosphonium ion intermediate in the presence of the amino group is the driving for
