Check Digit Verification of cas no

The CAS Registry Mumber 728034-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,0,3 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 728034-36:
(8*7)+(7*2)+(6*8)+(5*0)+(4*3)+(3*4)+(2*3)+(1*6)=154
154 % 10 = 4
So 728034-36-4 is a valid CAS Registry Number.

Synthesis of 4-monofluoromethylenyl- and cis-4-monofluoromethyl-L- pyroglutamic acids via a novel dehydrofluorination

Qiu, Xiao-Long,Meng, Wei-Dong,Qing, Feng-Ling

, p. 5201 - 5206 (2004)

Novel dehydrofluorination reactions accidentally found were used to synthesize terminal monofluoro olefin lactam analogues in good yield. The following hydrogenation of the resulting defluorinated product was systematically investigated. Two important fluorinated amino acids: 4-monofluoromethylenyl-L-pyroglutamic acid 16 and cis-4-monofluoromethyl-L- pyroglutamic acid 17 were synthesized using the methodology.
