98991-10-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98991-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,9 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98991-10:
(7*9)+(6*8)+(5*9)+(4*9)+(3*1)+(2*1)+(1*0)=197
197 % 10 = 7
So 98991-10-7 is a valid CAS Registry Number.

Tuning Rate of the Bergman Cyclization of Benzannelated Enediynes with Ortho Substituents
Alabugin, Igor V.,Manoharan, Mariappan,Kovalenko, Serguei V.
, p. 1119 - 1122 (2002)
matrix presented The Bergman cyclization of benzannelated enediynes is highly sensitive to ortho substitution. This finding opens possibilities for the rational design of conformer-specific and pH-dependent DNA-cleaving agents.
