Check Digit Verification of cas no
The CAS Registry Mumber 3660-91-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3660-91:
(6*3)+(5*6)+(4*6)+(3*0)+(2*9)+(1*1)=91
91 % 10 = 1
So 3660-91-1 is a valid CAS Registry Number.

Hydrazination of Pyridazines and Phthalazines
Counotte-Potman, A.,Plas, H. C. van der
, p. 1259 - 1261 (2007/10/02)
It is shown by 15N-labelling techniques that hydrazination of pyridazines partly occurs according to a reaction pathway, involving addition of the nucleophile (hydrazine), ring opening and ring closure (SN(ANRORC)-mechanism).It is also proved that phthalazines undergo hydrazination without ring opening (SN(AE)-mechanism).
