86997-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86997-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86997-25:
(7*8)+(6*6)+(5*9)+(4*9)+(3*7)+(2*2)+(1*5)=203
203 % 10 = 3
So 86997-25-3 is a valid CAS Registry Number.

ZUM MECHANISMUS DER SEMIBULLVALEN-BILDUNG AUS 1,2,4,5-TETRAZINEN UND BIFUNKTIONELLEN CYCLOPROPENEN
Schuster, H.,Sichert, H.,Sauer, J.
, p. 1485 - 1488 (2007/10/02)
A mechanism is proposed for the multi-step reaction of 1,2,4,5-tetrazines 1 and the bifunctional cyclopropene 2a to form substituted semibullvalenes 8.
