Check Digit Verification of cas no

The CAS Registry Mumber 1280227-55-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,2 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1280227-55:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*2)+(3*7)+(2*5)+(1*5)=135
135 % 10 = 5
So 1280227-55-5 is a valid CAS Registry Number.

Base-promoted selective aryl carbon-bromine bond cleavage by Iridium(III) porphyrin for Iridium(III) porphyrin aryl synthesis: A metalloradical Ipso addition-elimination mechanism

Cheung, Chi Wai,Chan, Kin Shing

, p. 1768 - 1771 (2011/06/22)

K2CO3 was found to promote selective aryl carbon-bromine bond (Ar-Br) cleavage by a high-valent iridium(III) porphyrin carbonyl chloride (IrIII(ttp)(CO)Cl, ttp = 5,10,15,20-tetra-p- tolylporphyrinato dianion) in benzene so
