Check Digit Verification of cas no
The CAS Registry Mumber 669081-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,8 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 669081-18:
(8*6)+(7*6)+(6*9)+(5*0)+(4*8)+(3*1)+(2*1)+(1*8)=189
189 % 10 = 9
So 669081-18-9 is a valid CAS Registry Number.

Trifluoroacetyl-Activated Nitrogen-Nitrogen Bond Cleavage of Hydrazines by Samarium(II) Iodide
Ding, Hui,Friestad, Gregory K.
, p. 637 - 640 (2007/10/03)
(Matrix presented) Trifluoroacetyl derivatives of hydrazines undergo clean and efficient reductive cleavage of the N-N bond with Sml2 in the presence of MeOH. After N-trifluoroacetylation, acyl-, aryl-, and alkyl-substituted hydrazines are redu
