1104608-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1104608-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,6,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1104608-07:
(9*1)+(8*1)+(7*0)+(6*4)+(5*6)+(4*0)+(3*8)+(2*0)+(1*7)=102
102 % 10 = 2
So 1104608-07-2 is a valid CAS Registry Number.

, p. 1329 - 1335 (2008)
Naturally occurring L-erythro-biopterin is synthesized using regioselective pteridine-ring formation from the chiral α,(β-epoxyaldehyde intermediate which is prepaccred from ethyl L-lactate via Sharpless epoxidation.
