82975-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82975-17-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,7 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82975-17:
(7*8)+(6*2)+(5*9)+(4*7)+(3*5)+(2*1)+(1*7)=165
165 % 10 = 5
So 82975-17-5 is a valid CAS Registry Number.

, p. 1253 - 1256 (2007/10/02)
Hydrazonation of 7-oxocephems 2a,b, followed by borane reduction of the resulting E and Z hydrazono compounds 3a,b and 4a,b, provided the key intermediates 5a,b, which were acylated to 6a,b and then deprotected to yield the 7-hydrazinocephalosporin deriva
