139955-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139955-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139955-09:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*5)+(2*0)+(1*9)=172
172 % 10 = 2
So 139955-09-2 is a valid CAS Registry Number.

REGIOSELECTIVE ANNULATIONS WITH RHODIUM(II)-STABILIZED VINYLCARBENOIDS
Davies, Huw M. L.,Hu, Baihua
, p. 453 - 456 (2007/10/02)
Construction of two series of cyclopentenes with predictable regiochemistry was achieved by means of rhodium(II)-catalyzed decomposition of vinyldiazomethanes in the presence of vinyl ethers.
