Check Digit Verification of cas no

The CAS Registry Mumber 1320194-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,1,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1320194-99:
(9*1)+(8*3)+(7*2)+(6*0)+(5*1)+(4*9)+(3*4)+(2*9)+(1*9)=127
127 % 10 = 7
So 1320194-99-7 is a valid CAS Registry Number.

Synthesis of carboxy-polyethylene glycol-amine (CA (PEG)n) and [1-14C]-CA (PEG)n via oxa-Michael addition of amino-polyethylene glycols to propiolates vs to acrylates

Song, Fengbin,Chen, Lu,Lin, Ronghui,Salter, Rhys

, p. 15 - 24 (2020)

Synthesis of carboxy-polyethylene glycol-amine (CA (PEG)n) via oxa-Michael addition of amino-polyethylene glycols to either acrylates or propiolates was investigated. Compared with the oxa-Michael addition to acrylates, the corresponding addition to propiolates was found to proceed under mild reaction conditions and afford the adducts in high yields from a broad scope of substrates. A two-step efficient and convenient synthesis of benzyl [1-14C]-propiolate from 14CO2 was therefore developed and utilized as a common synthon to afford practical and high yielding access to [1-14C]-CA (PEG)n.
