Check Digit Verification of cas no

The CAS Registry Mumber 894719-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,7,1 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 894719-52:
(8*8)+(7*9)+(6*4)+(5*7)+(4*1)+(3*9)+(2*5)+(1*2)=229
229 % 10 = 9
So 894719-52-9 is a valid CAS Registry Number.

Parallel synthesis of pyrazolines on soluble polymer support

Wang, Yan-Guang,Zhang, Jian,Lin, Xu-Feng,Ding, Han-Feng

, p. 1467 - 1468 (2003)

An efficient and rapid parallel liquid-phase synthesis of pyrazolines has been developed. The one-pot three-components reaction of polyethylene glycol (PEG)-supported acrylate 1, aldehyde 2 and aryl hydrazine 3 in the presence of chloramine-T in methanol gave the corresponding PEG-supported pyrazolines 5. Cleavage from the support under mild conditions afforded pyrazolines 6 in good yields (69-91%) and high purities (91-100%).
