918964-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 918964-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,9,6 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 918964-89:
(8*9)+(7*1)+(6*8)+(5*9)+(4*6)+(3*4)+(2*8)+(1*9)=233
233 % 10 = 3
So 918964-89-3 is a valid CAS Registry Number.

, p. 7000 - 7003 (2007/10/03)
Taming the insoluble: The reaction parameters of a β-peptide synthesis were optimized using only small amounts of reagents in a silicon microreactor (see picture). The use of unusually high temperatures (up to 120°C) reduces the reaction times. The insert
