87626-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87626-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,2 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87626-01:
(7*8)+(6*7)+(5*6)+(4*2)+(3*6)+(2*0)+(1*1)=155
155 % 10 = 5
So 87626-01-5 is a valid CAS Registry Number.

SYNTHESIS OF BICYCLODEC-2-EN-7-ONE VIA INTRAMOLECULAR PHOTOCYCLOADDITION
Seto, Hideharu,Hirokawa, Shinya,Fujimoto, Yasuo,Tatsuno, Takashi
, p. 989 - 992 (1983)
An efficient five step synthesis of bicyclodec-2-en-7-one by intramolecular photocycloaddition of 1-acetoxy-2-(pent-4-enoyl)cyclopentene and subsequent transformation sequence of the resulting cyclobutane derivative is described.
